This extract opens with a characteristic Sorabjian mediterranean dance with castanets, tambourines and harps. The static accompaniment in the strings (quasi strummed guitar?) building from 6-part bassi and celli adding each section until we have 17 parts and extremely high violin harmonics. Over this static accompaniment the violins start a sultry/languid tune and the wind and chorus take over. This reaches a peak (2’02”) which dissolves into quiet accapella singing and gong strokes which soon leads to another full bodied multi singing polyphonic section without the organ. During this passage a meandering quaver bass line starts (3’07”) which will dominate the next two sections. As the choir and upper strings fade away the persistent meandering quaver line emerges in the basses alone (3’48”) and then wanders it way up through the cellos, violas and 2nd violins. When it reaches the 1st violins it is then joined successively at octave intervals back down through the strings plus woodwind until we have four unison octaves which continue to descend and build into a huge polyphonic slightly disturbing Glory Glory section (5’36”). The organ re-enters, the meandering quavers continue in parallel harmony in the upper woodwind and violins, there are massive punctuating chords in the brass, the chorus sing the glory and there is a quasi-chorale like accompaniment in the lower wind and strings. What a marvellous section. The volume is pared down after a while and the chorale breaks up into more complex polyphony. Stamping percussion (7’05”) signal the climax of this section which abruptly breaks into rapid semiquavers in wind and violins with rhythmic marking of the beat in brass and percussion. The semiquavers get faster and faster building up through the whole orchestra before suddenly breaking off into….. (watch this space).

How one man could imagine all this music is unfathomable.


32 part chorus

Filed under: Uncategorised — David Carter @ 10:11 am

This excerpt features an extended choral passage where they divide from their usual 8 parts into 16 parts and then into 32 parts.

A quiet mysterious opening reaches a first climax at 1’32” at which point the lower strings start a rocking figure in parallel fourths which emerges from under the receding choir. Additional layers join up thorugh the strings until we have 10 stacked fourths and a nasty shout from percussion, piano & strings at 1’44”. A return to pleasenter stuff leads to the start of the choral passage at 2’12” at first in 8 parts and then 16 parts at 2’38”. I’ve rendered this passage, and much of this section, as quietly as possible. There’s a five part male chorus moment at 3’13” marked “[i]ferme bouche[/i]” . The VSL chorus samples don’t have ferme bouche (humming) samples so I’ve used “ooohs” instead of “aaahs” which I think works as a nice contrast. After another climax at 4’08” the 32 part chorus kicks in. As 32 staves of Sorabji’s manuscript paper were taken up with the choir the orchestral writing is very thin and for much of the time the chorus is acapella. The density of the writing is extreme and it’s hard to make sense of it. The best tactic (as is so often the case in this symphony) is to let the glorious sound wash over you. At 6’45” the chorus returns to 16 parts and the orchestra thickens out. A gradual build up leads to a climax at 7’40” and another return of the mighty organ and a signature passage which occurs several times throught the whole symphony, a “hallelujah” grand joyous noise for everyone.


New extract MS Page 591

This extract starts where the last one from 2013 ended. I hope the quality of the performance is better. It sounds better to me. One of the significant changes is to add a second microphone on the virtual stage. One is in the 7th row and the 2nd is where the conductor stands. I’ve also overhauled the settings in the virtual mixer which allows me to increase the presence of individual instruments and sections far more than I could before. Now I can have the choir dominate if I wish. The sound of the performance is from the perspective of a live performance and not a studio recording.

Of note is the return of the big chorus, organ and full orchestral ecstatic singing at 2’55” so characteristic of the symphony as a whole, and when this returns again at 4’24” it is proceeded by nothing less than a complete descending F major scale. This section peaks at 5’35” on a clear F major chord and is followed by a lovely rippling section in wind and strings. Some quiet clusters in the chorus, harmonics in the strings and pointilistic hocketing in the wind at 7’48” leads to a step up in the tempo at 9’15” and the final part of this extract, a vigorous section for rapid winds and loud brass with several aggressive fortepiano crescendo chords in the brass (really hard to pull off in Sibelius/VSL).

I could witter on for ever about how wonderful this music is. It is wonderful. It is also very different to the keyboard music. I believe it is much more accessible. I have read concern about Sorabji’s vertical harmony and melodic invention. Well this symphony has melody in abundance and clear and obvious vertical harmonic progression to satisfy the nay sayers. This extract has both to hear.


The Numbers of the Beast

Filed under: Uncategorised — David Carter @ 08:28 pm

In case there are any computer freaks listening in I thought I’d post the specs of my new PC. The components which make it possible to cope with the huge task of creating this virtual performance are 64GBs of top quality RAM, the high end processor and the super fast Solid State Drives for the operating System and the Sample drives.

Motherboard Asus Prime Z-370-P LGA 1151
Processor Intel core i7-8700K LGA 1151 3.7 GHz
RAM Corsair 64GB Vengeance LPX DDR4 2666 MHz
Graphics Card ASUS AMD Radeon R5 230 2GB
Audio Card Focusrite Scarlett Solo (2nd Gen) USB AudioInterface
Monitor 1 Samsung SyncMaster S27B350
Monitor 2 Samsung SyncMaster 2693HM
OS Drive Samsung 970 EVO V-NAND M.2 500GB SSD
Samples Drives OCZ Agility3 500GB SSD x 2
Cooling Fan Corsair Hydro Series H80i V2 Liquid Cooler
Power source Corsair RM750x 80 PLUS Gold

The software I use hasn’t changed other than the several updates over the years. Sibelius 8.2 and the Vienna Symphonic Library. I use the VSL Symphonic Cube sample collection. I have not moved on to their newer “Dimension” or “SYNCHRON-ized” sample sets, just too expensive. The main VSL software is the Vienna Ensemble Pro 6 (the virtual mixing console) and MIR Pro (the virtual concert hall where the virtual performers gather).


They’re Back!

Filed under: Uncategorised — David Carter @ 10:27 pm

I’m back on it. Following xmas 2018 I managed to get together enough finance to build me a monster PC. Once assembled I went straight into testing it on the remainder of the 3rd movement from where I had left off nearly six years ago. It quickly became apparent I was good to go and the new machine could cope with whatever I wanted to throw at it without compromise. Needless to say I was too excited creating the performance to worry about updating this blog and in any event I had forgotten usernames and passwords. Obviously I’ve now resolved that and can now regularly update the legion of followers of this blog and Sorabji fans worldwide (insert emotican for tongue in cheek here).

I know there are lots of broken links to earlier posts and I will get round to trying to sort that in due course but first I will post all the exciting stuff I’ve been doing in the last few months. Regular visitors to the Sorabji Archive forum will spot much duplication of posts there.


The Tuba Takeover

Filed under: Uncategorised — David Carter @ 10:30 pm

It’s been a long time because In May 2014 I was offered the opportunity to perform a tuba concerto with my orchestra The Forest Philharmonic Orchestra and one thing led to another and I’ve ended up commissioning a new concerto from Derek Bourgeois. That has in effect taken over my life and squeezed out any real time to spend on furthering the Jami. The WP of the Concerto is on Sunday 26th April 2015 at 6:30 at the Walthamstow Assembly Hall. And in January 2014 I joined East London Brass my local brass band and even though they are a fairly relaxed band, only rehearsing once a week, this has meant even less time for KS. It has revitalised my tuba playing which I had let slip almost to extinction over the last decade and I’m practicing more now than I ever have even in my music college days. Sorabji and Jami haven’t gone away though just been put on the shelf for a while. They’ll be back.


So Many Violins

Filed under: Uncategorised — David Carter @ 04:27 pm

Three and a half months since my last post during which I’ve completed a fourth section of just over 20 minutes bringing the total duration completed to 72 minutes of around 120 in 31 weeks suggesting it would take over a year to complete the whole of the third movement. However I’ve also decided to stop for the moment. Whilst I’ve been very excited that I now have the hardware and software to create the quality of virtual performance I want it’s become clear I don’t yet have the mastery of my tools to do it justice. What I have done is a quantum leap better than the first complete performance but I know it could be better and that with a greater understanding of the Vienna Symphonic Library and how to get the best out of it I could control so much better the quality of the sound and the ability to balance the music as I really want. My thoughts about interpretation have also changed since I’ve started.

At the moment I just can’t balance the various instrumental sections, melodic lines, solo moments as I want. There should be moments where the choir say or brass completely dominate the orchestra but I can’t do that to my satisfaction and I’m sure that is because of failings on my part in the way I have set up the software. I’m also sure I can get a better sound, particularly from the strings. So I feel I need to stop what I’m doing and go back to the drawing board with another project to try and learn better the tools of this trade. I’ve thought about finishing the third movement before doing that but that would still take a long time.

So, as this is not going to be my final performance/interpretation I shall let you have the totality of what I have done so far with the third movement. The most recent addition takes us to a pretty big climax. There are three major climaxes in this movement, the first at around 21 minutes the second at 72 minutes and the closing climax each of which gets progressively more massive. I’ve suggested before that the ending of this movement should probably be one of the most massive moments in all orchestral music right up there with Mahler 2 and The Gothic, but for the moment that’s for another day.

The most notable part of the new section is the extended passage where the violins divide into eight parts each i.e. 16 separate violin parts. That starts at 67 minutes in. With the score calling for 48 violins that’s three per part but VSL only gives me 12 player samples, 6 player samples and solo samples so as I’ve used the 12 player samples when the parts are divided into two parts (the majority of the work) and 6-player samples when divided into four parts (a substantial amount of time) I’ve gone for solo violins for the 16-part divisi which works for me. There were some difficulties in getting Sibelius & VSL to play 16 solo violin parts correctly at the same time (neither software was built for such a scenario!) but a work around was found. I had to be careful with the placement and balance to make the transition between two 12 player parts and 16 solo parts sound seamless and natural which I think I largely have done. I may well do another post quite shortly with a detailed musical description of how the 16 violin parts work – just cos I fancy doing that and I would like to get better at describing the music.

But for now here is the first 72 minutes of the third movement in flac and as mp3 – enjoy.

BTW the next project I will do, to improve my skills, is Sorabji’s Chaleur recently completed by Frazer Jarvis who has kindly let me have the Sibelius score.


The New Complexity? Phaw. Old Hat!

Filed under: Uncategorised — David Carter @ 02:19 pm

The third chunk of the 3rd movement is now complete. About 19 minutes. having returned to work which included a move of office across London and the kids returning to school it’s taken me seven weeks. I’m now up to 52 minutes so nearly at the half way mark.

I’m not sure when the term “New Complexity” was first applied to the works of Brian Ferneyhough, Michael Finnisy, James Dillon and Richard Barrett, but the Jami Symphony preceded them all and there are few pieces of even these composers which match the complexity of the Jami Symphony, except perhaps  Ferneyhough’s La terre est un homme – which only lasts 13 minutes!

A moment in this third part illustrates this complexity and I thought I would break it down between the various sections of the orchestra to demonstrate not only the complexity but the difficulty I am having in trying to make it as clear as possible. I work up each section one at a time woodwind, brass, chorus, strings, keyboards and percussion. Within each section I have to make choices about which part should be prominent and then which section should be prominent. Inevitably much is lost to the background wash, which is disappointing but choices have to be made. This section reaches a brief climax at roughly the overall mezzoforte to forte level and will be a long way from the massive climax at the end.

I had attempted to describe the complexity but decided it was easier toillustrate by splitting a particularly full passage into it’s constituent parts followed by the tutti version.





Keyboards, tuned & untuned percussion


As you will hear an awful lot of the detail is lost and in this section I have concentrated on the chorus at the start but allowed the brass to come through at the climax. I’ve made sure the tam-tam is heard because it is so rarely used but the woodwind detail is completely subsumed as is the piano (which hardly gets a look in in this work!). The strings are omnipresent! Whether these are the right choices who’s to say?

I still think the overall sound wash is exciting and there are plenty of places where lots of filligree detail can be heard.


Let the singer be heard

Filed under: Uncategorised — David Carter @ 12:55 pm

The second chunk of the third movement has been finished in record time as I’ve had some time off work and have been hard at it for several days. This section lasts just under 14 minutes and brings us to 35 minutes so over a quarter done. I’ve got three extracts for you.

 The first is the first entry of the organ in the third movement which as usual comes amid a fairly full orchestral and choral tutti.

 The second is the quotation from Chausson’s Symphony of 1890 played by the trumpets.

 The third is one of those very special moments of repose when over a quite sustained chord of B major (momentarily with added spice from the lower strings) four solo sopranos distantly sing a variation of the main theme before moving off into more Sorabjian tapestry.

 I continue to learn both the technology and the music. I’ve made some software setting changes which means I shall have to go back and do the first chunk again but I shall leave that to the end. I’ve found a way of balancing the sections better particularly the choir which needs to be more prominent and in the first part sounded almost like they were off stage. During this part I have also realised that the most important part of the music is the melody. There is always melody somewhere and often several. The textural stuff, whilst fascinating, must stand back and the melody must shine. The trumpet has several important melodic moments in this section. Even in the multi divisi string parts someone will have a melodic line whilst all around them go bananas and the emphasis should be on the melodic part.

 This whole symphony is one huge songfest.


Shaping up very nicely

Filed under: Uncategorised — David Carter @ 12:10 am

After seven weeks I have finished the first major chunk. The first 21 minutes. That’s quicker than I was expecting. The music is wonderful and I’ve two extracts to post. The first is a passage where the strings divide into 4, 4, 3, 3, 3. This features the VSL chamber strings with six violins, four violas, three cellos and two double basses per part. These passages tend be the strings providing a mosaic background to lyrical lines elsewhere. There’s a long melody in the tenor section over this. Listen for the lush 2nd violin four part glissando and the glorious top violin line later.

The second extract is an ecstatic full voiced moment for the choir divided into 32 parts largely supported by contrapuntal 10-part strings one of those joyous noise moments.

I’m still learning and improving as I go along and I shall want to go back and redo some earlier parts but intend for now to plow on. In particular I want to find a way to bring the choir forward in the mix, more in your face. At the moment they almost sound like their off stage and it’s very hard to make them loud enough in the big climaxes. And talking of big climaxes the end of this first 21 minute chunk is a real doosey. The problem is trying to rein in the excitement because the very end of the third movement is likely to be one of the biggest noises in any orchestral music right up there with the biggest moments in Mahler and even the Gothic. Way to go yet though.
