Piano is the companion sheet music book to Peter Kater’s 2003 Grammy-nominated CD of the same name. All eleven pieces are included and are placed in the book in the same order as they appear on the recording. Because of the improvisatory nature of much of Kater’s music, some of these pieces are quite difficult but worth the effort to master. Several pieces have what I consider excessively hard-to-read ledger line notes, so you might want to have a pencil handy to write in what some of those notes on “stilts” are. Most of the music includes the chords for improvisation, simplification, or for a guitar player to strum along with the piano. My favorite pieces to play have been “River,” “Summer’s Innocence,” “Trilogy,” and “Ascent.” The book can be purchased in a printed edition or as a download from peterkater.com. Individual pieces can also be purchased and downloaded. If you are fairly advanced piano-playing Kater fan, this book is a must!
