These excellent all-inclusive books teach scales, chords, arpeggios, and cadences at three different levels. The FIRST book (#11761) accommodates the learning pace of younger students such as those in Alfred’s Basic, Level 2. The BASIC book (#5754) is slightly more in-depth, presenting scales, chords, arpeggios, and cadence studies in all the major and minor keys. The COMPLETE book (#5743) features everything in the BASIC book, plus extra features like a 12-page explanation that leads to complete understanding of the fundamentals of major and minor scales, chords, arpeggios, and cadences; a clear explanation of scale degrees; and a two-page guide to fingering the scales and arpeggios.
