If you took lessons when you were younger, that word probably conjures up images of boredom, pain, and great suffering...
From their very first lessons my students are playing scales, chords, and arpeggios (even if in an abbreviated form). We frequently talk about the importance of these exercises, so that their minds don’t get lost in monotony.
For my beginner level students, I use "Scales, Pattern, and Improvs", published by Hal Leonard. Along with major and minor key five finger patterns, basic cadence chords, and over hand-arpeggios, there are also small sight reading and transposition exercises included in the book.
My more advanced students use "Scales, Chords, and Arpeggios", published by James Bastien. This book contains full scales in major and minor keys, cadences, and double-hand arpeggios.
