These are a series of piano studies to aid the piano student in sight reading in all the major and minor keys. The sheet music can be downloaded free in PDF format. The audio files can be downloaded free as mp3's. There is one prelude and one caprice in each major and minor key. Many technical exercises are incorporated in the pieces but they have enough musical value to be interesting to play. The complete book can be downloaded for free as 107 pages of PDF and the complete CD can also be downloaded for free. The sheet music was written with NoteWorthyComposer and the audio files are recordings of the playback by NWC. This leads to a precision that is an excellent starting point for the piano student but also leads to a complete lack of "feeling" which the student is thus required to create himself or herself.
