Every trainer, one place.

A cadence establishes the key, then a note plays - name the scale degree you hear and listen to it resolve home. One rep is one degree named and checked.

A scale plays ascending, root to root - name what you heard. Starts at major vs. minor in a fixed key, works up through any key, harmonic/melodic minor, and all seven modes.

A chord plays - name its quality. One rep is one chord identified and checked, starting at major vs. minor, working up through 7th and suspended chords.

Two notes play - name the distance between them. One rep is one interval named and checked, starting at five common intervals, working up through all twelve, harmonic and melodic.

A short chord progression plays - name its pattern. One rep is one progression named and checked, starting at the two most common pop progressions, working up to minor-key patterns.

A short melody plays - play it back on the on-screen keyboard, note for note. One rep is one melody transcribed and checked, starting at 3 notes, working up to 6 across the full range.

Predict where a tension chord resolves, or hear a progression and name its hidden chord. One rep is one answer checked, starting at V7 to I, working up to secondary dominants and deceptive cadences.

A note plays in tune, then again a little sharp or flat - set the slider to how far off you think it is. One rep is one guess scored in cents, from big 50-cent drifts down to hairline 3-cent ones.

A click plays at tempo - tap on every beat and see how close you land, in milliseconds. One rep is one timed run, starting at 70 BPM with a generous window, working up to 160 BPM tight.

A steady click marks the beat - tap the subdivisions in between from your own internal grid. One rep is one timed run, starting at eighth notes, working up to sixteenths at faster tempos.

Tap every beat while the metronome clicks less and less often - every beat, then every 2 beats, every bar, up to every 4 bars - at the same tempo. One rep is one tap, measured in milliseconds against the true beat.

You're given a chord symbol - no diagram, no audio - and pick the notes it's built from. One rep is one symbol spelled and checked, starting at major/minor triads.

You're given a scale name - no audio - and pick the notes it's made of. One rep is one scale spelled and checked, starting at major vs. minor, working up through modes.

A target pitch appears and you sing it from silence as fast as you can. One rep is a single attempt, scored on speed (ms to pitch) and accuracy (cents off).

A cadence sets Do, then you're told a degree by name - Re, Sol, Ti - and sing it from memory, no reference pitch. One rep is one degree sung and graded in cents.

A target pitch appears and you hold it steady for real, not just land it. One rep is one sustained note, graded on how long you held it and how little it drifted.

Turn each peg by ear until the string locks in against a reference tone. One rep is a full 6-string tune-up, graded in cents off target.

You're told a chord by name - no diagram, no reference - and you play it. One rep is one strum, graded on whether every note of the chord actually rang out.

An open-position chord gets strummed for real - name it. One rep is one chord identified and checked, across the eight classic open major and minor shapes.

A position lights up on the neck - name the note. One rep is one position named and checked, starting at open strings and the first 3 frets, working up to the whole practical neck.

You're given a scale and a fretboard position - is that note in the scale, or not? One rep is one call made and checked, starting at the major scale in one key, working up through modes.

A click plays at tempo - pick the target string on every beat. One rep is one timed run, graded on how many beats landed on the right string, right on time.

A backing drone sets the key, then you're told a note - land it anywhere on the neck before time runs out. One rep is one target, starting at minor pentatonic, working up through all seven modes.

A major scale is laid out as tab - study it, then play it for real. One rep is one scale played and checked note by note, starting at E major open position, working up to any key, ascending and back down.

A minor pentatonic shape is laid out as tab - study it, then play it at your own pace. Each note is listened for in order, and it moves on the moment you play it right.

You're given a note name - find it on the keyboard. One rep is one key found and checked, starting at white keys in one octave, working up to exact notes across three octaves.

You're given a chord symbol - click every note it's built from, in any octave. One rep is one chord built and checked, starting at major/minor triads, working up through 7ths and suspended chords.

You're given a scale name - play it ascending, root to root. One rep is one scale played and checked, starting at major vs. minor in a fixed key, working up through modes.

A pattern plays across two registers, switching hands - play it back in order, on the correct side. One rep is one pattern echoed and checked, starting at 4 notes, working up to 10.
