Please contact me for more information should you wish to purchase any of these. They are all between level II and III in the jazz education standard of grading unless itgerwuse stated (medium hard). All arrangements can be easily adapted for other voicings (if you have too many sopranos, for example)...let me know and I'll get that done for you. Links direct you to an image of a page (or two) of each arrangement.
I have made practice tracks for each of these arrangements (which come with your purchase). Each track is mixed with a Karaoke-style rhythm section, and with the part that requires the practice in your left ear and all the other parts in your right ear).
