Trichord Trainer

Tonal Ear Training x Spaced Repetition

Trichords

Any combination of three notes: arpeggiated or blocked, spanning up to a major tenth. Over 19,000 different cards to learn.

Tonal Training

Hear notes in relation to any key center, not in isolation. A scale or arpeggio establishes the tonality before each group of cards.

Spaced Repetition

A science-supported technique using the same algorithm as Anki. It decides which cards need the most practice for you.
