## What is Clefs?

Learn to read sheet music fluently. Quick daily exercises, a guided course, and smart review take you from your first notes on the staff to instant recognition in every clef.

Clefs is a focused note-reading trainer: no filler, just the skill that unlocks everything else in your musical life. Whether you're starting piano, joining a choir, switching to viola, or finally fixing the bass-clef gap you've had for years — a few minutes a day builds real reading fluency.

WHAT YOU GET
• A step-by-step course: from the treble staff to key signatures, ledger lines and beyond, with exams to prove your progress
• Smart practice that remembers you: spaced review brings back exactly the notes you're about to forget
• Reading AND writing drills — recognize notes on the staff, then place them yourself
• All ten clefs: treble, bass, alto, tenor, soprano, mezzo-soprano, both baritones, French violin and sub-bass
• A daily goal, streaks with freezes, and reminders that adapt to your routine
• Detailed statistics for every clef and every note

MADE FOR MUSICIANS
• Connect a MIDI keyboard and answer on real keys
• Warm sampled piano sound, precise notation, custom exercises with your own clefs, key signatures and timers
• Built-in theory guide when you want the "why" behind the notes

START WHERE YOU ARE
A short placement test finds your level, so day one is neither boring nor overwhelming. New notes are introduced gradually, consolidated with review, and tested when you're ready.

ONE PURCHASE, EVERYTHING FOREVER
No subscription. A single one-time upgrade unlocks the full course, all clefs and the exercise editor — free content lets you build the habit first.

Reading music is not a talent — it's a practice. Start today.
