Hidden within all of the 10 innovative piano solos in each volume are scalesÂ--sometimes ascending, sometimes descendingÂ--in one or both hands. What makes each book Â"Not Just Another Scale Book,Â" however, is the accompanying CD that features wonderfully orchestrated background tracks. Book 1 features pieces written in both major and minor keys up to two sharps or flats. Book 2 has pieces written in major and minor keys using three to seven sharps. The pieces in Book 3 are written in major and minor keys using three to seven flats. Titles: Cry of the Whippoorwill * Downtown Groove * Enchanted Lake * Irish Festival * Jamaican Breeze * Midnight Forest * Mountain Sunrise * Rainy Day Blues * Sailing the Open Sea * Star Gazing.
