Harmony Finder is a word search for music. Instead of words, you hunt for a chord or scale hidden in a grid of numbered, colored squares.

Start options

• Tonic is the home note. Every number in the grid counts half steps up from it: 0 is the tonic, 4 is four half steps above, and so on. The colors show the actual pitch.
• Voices is how many notes you are hunting for, from 3 to 8: 3 for a triad, 4 for a seventh or sixth chord, 5 for a ninth, 6 for an eleventh, 7 for a mode, 8 for the bebop and diminished scales.
• Quality is which chord or scale to find. The list changes with Voices, and each choice shows its numbers beside its name.
• Instrument is the sound the notes play with. Vibraphone is the default.

Solving

• The Search: key at the top shows the numbers to find. Press ▶ Play to hear them. Tap one to hear that note and see where it sits in the grid.
• Look for those numbers side by side in a straight line: across, down or on an exact diagonal, either direction, in any order, each number once.
• Drag from the first square to the last. A correct find is circled and played. Finds can cross and share squares.
• The counter shows how many you have found. Find them all to hear the finale, and press Play to hear it again.
• Stuck? Show outlines the ones you have not found, and Hide puts them away. New, at the far right, starts over with fresh settings.
