This play along covers Dominant 7th chords in all 12 keys. I’ve been enjoying using these tracks in both my personal practice and teaching for a while.
The bass and drums swing at 120bpm in 4/4 time while a dominant 7th shell voicing (root, 3rd, b7th) drones in the background.
This type of play along has been done before, but the use of the live bass and drums combined with a drone of the Dominant 7 shell voicing (root, 3rd, b7) makes it really easy to hear the Dominant 7th sound.
Also, since the tracks have minimal rhythmic comping from a chordal instrument I find these play alongs less distracting when working on ear training or a specific phrase, scale or melodic idea.
Since each track is only a shell voicing plus bass and drums, you can play any type of dominant 7th chord or chord scale when practicing.
For example, you can put on the C7 play along (below) and improvise using C7 mixolydian, lydian dominant, altered, b9 – b13, H.W. diminished, whole tone, or any other dominant 7 chord scale, or just play free over the dominant 7th sound.
Each track plays for 5 minutes, and you can pick just the dominant 7th shell drone (root, 3rd and b7th) or the Drum and Bass plus dominant 7th shell drone (24 tracks in all).
You can download the mp3s from CD baby here or find them on any of the common online mp3 distributors.
