Three Octave Progressive Cycle Scales
These are play-along scales that I created for my own practice and still use. I've also seen students improve their intonation significantly after spending some time working with these scales regularly. Each play-along scale is about 17 minutes long and begins with an open “G” tuning note. The scale cycles progress from slower to faster with a high hat indicating the speed of the faster tempo. There is an organ sound in addition to the more percussive piano at the slower tempos so you can really listen to where the notes fit within the harmony.
