Many of the concepts are also demoed by saxophonist Tony Bray at the end of the lessons. The topics covered include: - How to fully realize the bebop scale through strategic placement of half steps to ultimately include all twelve notes of the chromatic scale while maintaining appropriate chord colors. - How to develop longer phrases. - Turnarounds and chord substitutions. (Includes tempo adjustable examples that loop and transpose for practicing over.) - A breakdown of the Confirmation sequence. - Various approaches to playing over I Got Rhythm changes. JAM-A-longs include individually created files for each key. Each will loop indefinitely, all keys are covered and tempos are adjustable. The included JAM-A-longs are: - V7 - II V I - I Got Rhythm 1 - I Got Rhythm 2 - Confirmation Sequence - Turnaround 1 - Turnaround 2 - Turnaround 3 As with other other Jazz Apps Mobile apps, you can set the notation clef and the overall transposition for your specific instrument and there is balance control for the JAM-A-Longs.
