So here’s a 7 bar Excerpt from John Coltrane’s Tune Giant Steps

[ Bmaj7     | Fmin7   Bb7 | EbMaj7      |  Amin7  D7  |  Gmaj7      |  C#Min7  F#7  | BMaj7    ]

Set up a metronome and practice the following layers

• Root on the 6th String
• Root on the 5th String
• Root on 6th string plus 7th
• Root on 5th string plus 7
• Root on 6th string plus 3rd
• Root on 5th string plus 3rd
• Root on 6th string plus 3rd and 7th
• Root on 5th string plus 3rd + 7th
• Root on 6th string plus 3rd and 7th without Root
• Root on 5th string plus 3rd + 7th Without Root
• Playing any 3rd + 7 th voicing and transition to the next nearest one

These layers might seem excessive, but they internalise your knowledge of the fretboard and your ears knowledge of the sounds.
