Organ Symphony Assistant is a collection of audio files that recreates the complete orchestration of some of the great masterworks written for organ and orchestra. These recreations are designed to be played while you play the organ part. You will find over 35 separate works for organ and instrumental ensembles of various sizes and combinations.

How it all started

Many years ago, a dear colleague had decided age had gotten the better of her keyboard skills and it was time to give up much of her organ music. It was offered to me and among this very nice collection was the Organ Concerto in G Minor by Francis Poulenc. It looked in perfect condition.  I knew the piece well and was excited to have it.  However, much like it did with my friend, the score remained untouched, now tucked away in my collection.  I would look at it periodically but, because of the very slim chances I would have to perform it, never felt the inspiration to work on it.

Having used technology as a tool for composing choral scores, I began experimenting with the process of transcribing orchestral scores. My first attempt was the First Organ Concerto by Josef Rheinberger. It is a small orchestration with fairly traditional harmonies and rhythms.  The results were credible enough for me to continue the experiment. 

I began work on the Poulenc Organ Concerto score.  I knew this transcription would be challenging but I moved forward.  After completion and a first listening, I was excited and, for the first time, inspired by what I heard.  The Poulenc Organ Concerto score that had remained untouched for so many years was finally going to be learned and played

It was then that Organ Symphony Assistant was born. 

What is Organ Symphony Assistant? 

Organ Symphony Assistant (OSA) is similar to the "Music Minus One" Series, created in 1950 and still widely in use today.  A recording (usually available as a CD) is made "minus" you, the soloist. "Music Minus One" users get to play along with a full orchestration of masterworks, like many of the great piano concertos that we know and love.  Unfortunately, there has never been anything created for the great masterworks written for organ and orchestra.   

What makes OSA audio files different from Music Minus One is the player has more extensive options for editing the orchestra parts.  Although the audio scores have been edited for dynamics, tempi, etc., and are "performance ready", further changes can be made by you.  Also included are OSA-edited sheet music organ scores specifically designed to be used with the OSA audio files.

Additional pieces are always being prepared.  If you have a piece you would like to see as part of the OSA collection, let me know.   

If you have ever given thought to the possibility of studying any of these great pieces,  I hope Organ Symphony Assistant will give you the desire and inspiration.  Please click the "Getting Started" link below to learn more.
