The feature,
explained clearly
Practice Mode is the open ear training space inside Earonman. Ten different drill modes in one place: four foundational modules (Intervals, Chords, Scales, Jazz Voicings) available to everyone with a free foundation library, plus six advanced quest modes unlocked with PRO. No levels and no daily cooldown, and nothing you get wrong costs you anything - you pick what to train and how long. Correct answers still earn XP and keep your streak.
Four free foundation modules
Intervals, Chords, Scales, and Jazz Voicings - the fundamentals of relative pitch and harmony, free with no daily cooldown. Covers intervals up to the octave, triads and 7th chords, major scale modes, and basic jazz voicings.
Six advanced PRO quest modes
Slashmaster for slash chords, Functioneer for harmonic functions, Harmonic Quest for harmonic movements (Barry Harris style), Guido for guide tones over jazz progressions, Hybrid Lab for triad-over-bass voicings, and Polychordist for stacked triads (polychords).
No daily limit
The gamified Exercises have a 3-per-8-hour cooldown on Free. Practice Mode does not - on either free or PRO modules. Drill 5 exercises or 500, whenever you want.
Rewards effort, punishes nothing
Every correct answer earns XP and keeps your daily streak alive, so the reps count for something. But wrong answers cost nothing, and practice XP stays out of the weekly leagues and the leaderboard - the pressure-free space to actually push your limits.
Custom filtering inside every mode
Pick exactly which intervals, which chord qualities, which modes, which voicings, or which slash patterns to train. Narrow down to one specific weakness and drill it.
Real piano sound across all modes
Every Practice Mode exercise uses the same Petrof III grand recordings as the rest of the app. Whichever module you drill, you train on professional grand piano timbre.
Three steps.
Repeated until it sticks.
Three taps from opening Practice Mode to your first exercise.
Pick one of ten modes
Choose any of the four free modes (Intervals, Chords, Scales, Jazz Voicings) or, on PRO, any of the six quest modes (Slashmaster, Functioneer, Harmonic Quest, Guido, Hybrid Lab, Polychordist).
Filter what you train
Set up the session - narrow to specific intervals, specific chord qualities, specific modes, or specific voicing families. Restrict to one inversion or include them all.
Drill until you are sharp
Random exercises pulled from your chosen content. Answer as many as you want. Step away whenever. Your stats record everything for later review.
Skills you walk away with
Practice Mode is a tool for building relative pitch and harmonic recognition. The skills you build here transfer directly to transcribing, improvising, composing, and playing music by ear.
Reliable interval recognition
Train any interval combination from simple seconds to compound thirteenths. Build the instant recall that transcription demands.
Full chord vocabulary
Every triad quality, every seventh chord type, every inversion. The kind of vocabulary that lets you call out chord changes by ear on the bandstand.
Modal and scale recognition
Hear the colour of each church mode - Dorian, Mixolydian, Phrygian, Lydian. With PRO, hear the same way the melodic minor and harmonic minor mode families work, plus bebop and symmetric scales.
Jazz voicing identification
Hear Closed Position, Shell Voicings, and Left Hand Voicings in the free module. With PRO, drill the full library - Drop 2, Drop 3, So What, quartal stacks, Shearing block chords.
Advanced harmonic devices (PRO)
With PRO, the six quest modes drill slash chords, harmonic functions, harmonic movements (Barry Harris style), guide tones over jazz progressions, hybrid voicings, and stacked triads (polychords). The advanced jazz vocabulary, gamified.
Targeted weak-spot drilling
Stats from your gamified exercises tell you where you are weak. Practice Mode lets you drill exactly that, unlimited, without burning curriculum cooldown.
Daily reps.
Compound results.
Practice Mode is the closest analogue to the way professional musicians actually maintain their ears - daily, focused, targeted, with no scoring pressure. Treat it as the gym for your ears.
Targeted drilling beats random reps
Random practice is fine for beginners. Once you know your weak spots, targeted drilling produces results 3-5x faster than open-ended sessions.
The pressure-free space matters
When a score or a streak is on the line, your brain plays it safe and reaches for the easy answer. Practice Mode keeps the rewards but removes the risk - nothing you do here can be lost, so you can actually push your limits.
A real free foundation
Earonman gives an actual usable Free tier - intervals up to the octave, triads and 7th chords, major scale modes, and basic jazz voicings - without a daily cooldown in Practice Mode. Enough to develop reliable relative pitch before deciding whether to upgrade.
Maintenance is a separate skill from learning
Once you have learned a chord type or interval, you have to maintain it. Practice Mode is the maintenance gym - low pressure, infinite reps.
Not just jazz musicians
Practice Mode is for any musician who wants better ears, regardless of style or experience level. Especially valuable for these groups.
Working jazz pianists
Free voicings before a gig, plus PRO quest modes (Slashmaster, Hybrid Lab, Polychordist) for the advanced comping vocabulary working pros actually use.
Composers and arrangers
Build the internal sound library that lets you hear an arrangement before you write it. Hear which extension or substitution will land.
Producers and beatmakers
Identify chord progressions in samples and reference tracks. Train your ears to hear when a layer is in the wrong key or fights the harmony.
Classical musicians
Sightsinging, intonation, transcription, sight reading. The same skills conservatoire exams demand, on a free unlimited platform.
Self-taught musicians
Close the blind spots most self-taught players have around tritones, sevenths, and inversions. Free unlimited reps until it sticks.
Hobbyists who never plan to subscribe
Earonman is genuinely useful on the Free plan. Practice Mode alone is enough to take an absolute beginner to recognising 7th chord qualities, free forever.
Free forever.
