TONARIO: Relative Pitch

Stop counting intervals. Hear what each note does inside a key. Train movable Do, cadences, melodies, and tonic recognition across changing keys and timbres.

Hear what a note means—not just how far it is from the last one.

TONARIO is functional ear training built around movable Do. The tonic is always Do, helping you recognize stability, tension, color, and resolution inside a key—even when pitch height and timbre change. Build that skill step by step across 28 stages.

WHAT YOU CAN TRAIN

• Compare each note with the tonic over a continuous drone • Establish the key with I–IV–V–I cadences • Practice in all 12 keys, five timbres, wide ranges, and timed sessions • Transcribe everything from single notes to eight-note melodies with movable Do or scale degrees • Explore b7, #4, minor, and V7–i beyond the major diatonic scale • Find the tonic of an automatically generated musical excerpt from all 12 pitch classes • Hear a missed note resolve toward stability and reinforce its function

DESIGNED TO RESIST MEMORIZATION

Keys change by block and, in advanced stages, on every question. Timbres and registers change too, so memorizing “this pitch is Do” or “this instrument sound is Sol” is not enough. Your attention stays on the tonal center and on where each note wants to rest or resolve.

SEE YOUR PROGRESS

Practice in focused 20-question blocks and earn stars as you advance. Review accuracy by scale degree, response-time trends, and accuracy by key to find the notes that need more attention. Add your own impressions to the Sound Journal and build a personal vocabulary for every tonal function.

MADE FOR

• Musicians who want faster, more reliable transcription by ear • Singers who want to hear pitch inside the key • Improvisers and composers exploring melodic and harmonic function • Students connecting solfege, aural skills, and music theory to real sound • Anyone building a relative-pitch skill that transfers between keys
