Click a node (or the octave selectors to the right of each node) to play pitches. All nodes default to within one octave above the fundamental. Use the control panel to control the sound, how pitches are displayed, which primes are displayed, and to locate specific intervals. Copyright © Alexander Garsden 2025.
*Pitch example: A4 +0c (Octave 4 assumed if not specified, e.g. A +0c)
Highlight all nodes within a specific pitch class range (ignoring octaves).
Find pairs of nodes matching an interval. Use a preset or enter a ratio manually.
