## What is Bass Clef Master?

Struggling to read bass clef? You're not alone.
  
  Bass Clef Master is a dedicated sight-reading trainer for bassists, cellists, trombonists, and
  anyone learning the bass clef. Our 6-level system takes you from zero to confident reader in 6
  months.

  A few minutes on your commute or during a break — played like a game, progress adds up faster
  than you'd expect.

  It goes beyond reading notes on a page. Practicing with Fretboard Input mode wires your
  fretboard, note names, and sheet music together at once — giving you a deeper whole-neck
  understanding no other sight-reading app offers.

  【3 Practice Modes】

  - Practice Mode: Random notes flash on the staff — tap the fretboard or enter the note name.
  Track your combo and personal best as you level up.
  - Time Attack: Answer as many notes as possible in 60 seconds. Watch your reading speed grow
  with each attempt.
  - Phrase Mode: Read through real bass-style phrases note by note. 17 presets included (7 free +
   10 Pro), plus custom import support.

  【6 Progressive Levels】

  Lv1: Open-position notes (0-3 frets)
  Lv2: Mid-position notes (~5 frets)
  Lv3: High-position notes (7-12 frets)
  Lv4: Full range — all 17 natural notes
  Lv5: Sharps and flats — lower range
  Lv6: Sharps and flats — full range master

  5-string bass (Low-B) supported. Every note in the bass clef, covered.

  【2 Input Methods — Both Free】

  - Fretboard Input: Tap the string and fret like you'd actually play it. The repeated loop of
  reading the staff and touching the neck burns note positions into memory, linking sheet music
  and fretboard in your brain.
  - Note Name Input: 7 buttons (C-B) with sharp/flat modifiers for fast entry.

  【Built to Build Habits】

  - Daily Streak: Track consecutive days of practice
  - Achievements: 8 unlockable badges to celebrate milestones
  - Stats Dashboard: Accuracy by level, input method, and time attack high score (Pro)
  - Daily Reminder: Optional 9 PM push notification
