These lessons consists of chord progressions used in popular pop/rock/r&b/folk/blues songs from the 1950's to the 1980's and can be used as sight reading exercises, left and right hand co-ordination exercises, ear training exercises to hear the chord progressions, use these keyboard rhythm parts when playing with other musicians. I use these progressions with my students to help in their piano/keyboard techniques. Each progression consists of 1. Video of the music, 2. PDF of the music with an MP3 file of the keyboard part with rhythm section and play-a-long track to practice the progressions with. 3.MIDI file so that you can transpose the progressions and practice in different keys.
