There are quite a few little pieces for guitar including what I believe is the first transcription for solo guitar of the lovely little Adagio in F by J Haydn which you can buy for $5.00 US.
There is also a short piano piece in the style of Philip Glass.
I also have ready to upload a wind quintet which is a Homage to a musical acquaintance of mine, still young being in his 40s, who has unfortunately contracted an incurable cancer and is not expected to live for much longer.
Currently I am working on a piece called " Passion Play" scored for string quartet which is sounding interesting.
Apart from Haydn's Adagio, the rest of the guitar compositions are free, so please do take the opportunity to print them off for your own or your student's use if you would like.
