Here is the sheet music for my organ sonata, composed for a recital I gave in November 2014. I hope to go back and record it, but that will happen in the summer (at the earliest) when the church is warmer and thus more conducive to practicing.
The stop list (at the back) are the stops I used, and along with the dynamic markings should give an indication of the colour intended, but as with all organ music the organist must feel free to use their own imagination for the registration.
