Hidden within all of the 10 innovative piano solos in each volume are scales - sometimes ascending, sometimes descending - in one or both hands. What makes each book 'Not Just Another Scale Book,' 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. 32 pages.
