I am also a composer for piano. I am presently putting together two book of my pieces. The first book will target the first few levels of piano skill. The second will contain pieces of a greater difficulty. They each should be about 70 to 80 pages in length and become available by spring 2012 (Book No. One) and autumn 2012 (Book No. Two).
A workbook for basic beginning piano composition is also in the works. It should be available in the spring of 2012 and will be used in classes I will teach. I have accordingly scheduled a workshop for beginning piano composers for April 17, 2012 to be held in the central part of the Salt Lake City Metropolitan area. It will begin at 10 a.m. at a location to be posted later.
