Bartók Triad Pair Drone

Build and hear Bartók-style triad-pair drones from two three-note JolyMusic chords or scales, selectable intervals, inversions, and registers.

Build a Bartók triad-pair drone

Choose a key and three intervals for the lower and upper chord-or-scale cells, set their registers, then hear the combined color as a sustained drone.

What to listen for

Hear the low inversion as the ground. Then notice how the higher cell avoids functional resolution and turns both chords or scales into one chromatic atmosphere.

Why this creates a Bartók-like color

The default C and D♭ major cells have no common pitch classes. Their adjacent roots create semitone pressure, while the opposed inversions and register separation keep the result suspended rather than cadential.

  1. Start with the default drone and identify the lower C cell.
  2. Focus next on the higher D♭ cell without changing the bass.
  3. Change one interval at a time and compare strict six-note pairs with shared-tone pairs.

Generated journey events

Tempo, meter, sections, and triad-pair harmony are stored on the same global-event and harmony lanes used by Instrument Show.

Bottom transport is the timing master. Click a triad-pair zone to select its Studio station. Timing, loops, and playhead remain transport-controlled.
