What you can do in Earsharp on the web
Interval drill, all twelve
Beginner, intermediate or all 12 intervals, played ascending, descending or as a real harmonic dyad — both notes on the same tick.
Chords played harmonically
Triads, 7ths and sus chords sounded together rather than arpeggiated, because identifying a stacked chord is the whole point.
Scales and modes
Major, natural / harmonic / melodic minor, all five remaining modes and both pentatonics — eleven scale kinds, banked so you can start small.
Melodic dictation and rhythm clap-back
Hear a 3–8 note phrase and tap it back on a two-octave keyboard, or hear an eight-slot rhythm and tap it back — graded TIGHT / OFF / WRONG with your average deviation in milliseconds.
Randomisation that actually works
Every question you miss gains 0.75 weight and comes round sooner; every one you nail decays it again. Switch the weighting off if you want flat random.
Honest counters, nothing else
Today and lifetime right-out-of-attempted per drill, a fourteen-day answer chart and a list of the questions you keep missing. No streak, no badge, no leaderboard.
