By understanding and practicing displacements exercises, you will develop greater technical proficiency and creative expression. Incorporate these techniques into your practice routine to explore new musical possibilities.

Pentatonic Scale Used:

  • Modes of the G Major/E Minor Pentatonic: The phrase starts with a G major pentatonic at the 12th fret, descending and following the modes starting from G, D, B, A, G.

Displacement:

  • Definition: Shifting the starting note of the scale pattern to create different rhythms, syncopation and groupings.
  • Purpose:

Notes Groupings:

  • Shift the starting point of the scale within the measure. Play the G major pentatonic scale descending, ensuring the starting note of the next mode is the end of the previous phrase.

Rhythmic Displacement:

  • Example: Repeating the starting note twice to shift the scale shape and ending the entire phrase with quarter note triplets using a B minor 7th arpeggio.

Practical Exercise:

  • Displace the G major pentatonic scale (and all its modes) starting from different notes each time and at different beats within the measure.
  • Exercise: Play the G major pentatonic scale starting on the B note (4th fret, G string). Descend using the following sequence: BAGE DBAA (last A is an octave higher) GEDB AGE.

Applying Pentatonic Displacement

Improvisation:

  • Use pentatonic displacement to create solos and bass lines that stand out.
  • Experiment with different starting points and rhythms to add variety.
    • Example: Start improvising from the 7th fret of an Emin chord, use the Emin pentatonic and displace the starting note every two beats to create a shifting rhythmic feel.

Bassline:

  • Apply pentatonic displacement techniques when writing bass lines.
  • Create interesting and complex bass parts by displacing scales and altering rhythms.

Practice Tips:

  • Start slow and gradually increase the tempo. These exercises can be challenging if you haven’t done them before. Ensure you have control of the shapes before attempting with a drum loop.
  • Use a metronome to keep time and gradually increase the speed as you become more comfortable with the technique.
  • Record yourself playing and listen back to identify areas for improvement.
