Book excerpt: Learn the secret to playing long, flowing musical lines that move from one chord change to the other in a smooth, seamless manner. This book explains "approach tones" (a tone or series of tones leading to a chord tone of the next chord---usually by a whole or half step) and "target tones" (tones that resolve your phrases and outline harmony). All great jazz players use this technique to create forward motion, tension / release, and play musical solos that sound "right."
