Metronome

Getting Started

• Start/Stop: Click the "Metronome" pulse or the Start/Stop button
• Set Tempo: Click the BPM number to open the tempo slider and quick presets
• Choose Sound: Select from the dropdown (Beep, Bass, Cymbal, Tock, Riffs, Vibrate, or Silent)
• Change Theme: Click the colored circle in the top-left corner

Visual Indicators

• Metronome (left pulse): Flashes on each beat to keep you in sync
• Your Beat (right meter): Shows your tapping/movement intensity in real-time
• Tap the "Your Beat" meter to enable/disable beat detection

Beat Detection Mode

What it does: The metronome monitors your movements and only makes sound when you drift off tempo. Perfect for practicing independence and staying on beat!

How it works:

• Enable by checking "Beat Detection" or tapping the "Your Beat" meter
• The metronome runs silently while you practice
• Your device's accelerometer detects taps/movements
• The system evaluates both timing and tempo:
  • Timing: Are you within tolerance of the beat? (in milliseconds)
  • Tempo: Is your overall BPM within range?
• If you're on beat → Silent (green status)
• If you drift off → Metronome beeps to guide you back

Beat Detection Settings

These appear when Beat Detection is enabled:

• Beat Detection (0-100%): Motion sensitivity
  • Higher % = detects lighter taps
  • Lower % = requires harder hits
  • Default: 50%
• Timing Tolerance (5-1000ms): How precise your timing must be
  • 100ms = within 0.1 seconds of the beat
  • Lower = stricter timing required
  • Higher = more forgiving
• BPM Tolerance (0-20): How consistent your tempo must be
  • 5 BPM = stay within ±5 BPM of target (e.g., 115-125 when target is 120)
  • 0 = must match target exactly
  • Higher = more tempo drift allowed

Pro Tip: Focus on one skill at a time!

• Practice tempo consistency: Set Timing Tolerance to 1000ms (max)
• Practice precise timing: Set BPM Tolerance to 20 (max)

Status Display

When Beat Detection is active, you'll see three indicators at the top:

• Status: "On beat" (green) or "Off beat!" (red)
• Detected BPM: Your actual tempo based on your taps
• Accuracy: Milliseconds off from the metronome beat

Tempo Control

Click the large BPM number to open a menu with a tempo slider and quick preset buttons for common musical tempos:

• 60 - Largo, 72 - Adagio, 80 - Andante, 92 - Moderato
• 108 - Allegretto, 120 - Allegro, 132 - Vivace, 144 - Presto
