This book is designed to assist elementary and intermediate-level keyboard students in learning basic melodic and harmonic keyboard patterns. Patterns include major and minor pentachords in all keys, scales built in tetrachords in all keys, major and minor triads in arpeggio form, various basic chord progressions, blues scale patterns, and the blues chord progression. Essential Melodic and Harmonic Patterns also contains jazz comping (chord accompaniment patterns) techniques and helpful suggestions regarding melodic improvisation. Such activities encourage creativity and ear development. All melodic and harmonic patterns are completely notated for the student. However, the goal is to have students eventually internalize each pattern. When patterns are learned and become second nature, students will become more secure players. They will recognize familiar melodic and harmonic shapes. Such recognition will benefit skills in sight reading, analysis, transposition, and even improvisation. Included is a  CD with both audio and General MIDI File accompaniment tracks.
