Example4a ROOT PEDAL TONE WITH DIATONIC CHORDS (DORIAN)
We now take the opposite approach to Example 3 (which fixed an upper chord and moved the bass). Here we fix the bass, to create a ‘pedal tone’, and move the upper chords resulting in a series of slash chords. This is a particularly useful technique in establishing a mode so that the intended root of the mode is always heard, and the ear is ‘anchored’. This example is in A Dorian, there is an A pedal tone, and the upper chords are diatonic (from the key) of A Dorian. You can hear a similar idea in Kenny Burrell’s Midnight Blue, Bon Jovi’s Wanted Dead or Alive and Van Morrison’s Moondance.
