Musician Tools
Built-in tools for practice and creativity. Tune your instrument, keep time, explore music theory, compose chord progressions, and get real-time improvisation suggestions.
Overview
Band Jams includes five musician tools accessible from the Tools page. Each tool is designed to support your practice sessions and creative workflow without leaving the app.
Tuner
Pitch detection and reference tones for accurate tuning.
Metronome
Tempo and rhythm practice with visual beat feedback.
Music Theory
Chords, scales, and circle of fifths explorer.
Chord Composer
Build and export chord progressions with intelligent suggestions.
Improviser
Live chord detection and scale suggestions from your microphone.
Tuner
A chromatic tuner with two modes: mic-based pitch detection and a reference tone generator.
Tuner Mode
Uses your microphone to detect the pitch of your instrument in real time. Color-coded feedback shows whether you are in tune: green for in tune, yellow for close, and red for off.
Tone Generator
Play reference tones to tune by ear. Choose between sine wave (pure tone) or guitar waveform (with harmonics) for a more natural sound.
A4 Frequency Presets
Metronome
A full-featured metronome with tempo range from 20 to 300 BPM, configurable time signatures, and subdivision options.
Tempo & Presets
Set any tempo from 20 to 300 BPM. Quick-select presets are available for common tempo markings from Largo through Presto. Use tap tempo to match an existing rhythm.
Time Signature
Configure beats per measure (1 to 16) and note value (half, quarter, eighth, or sixteenth). Toggle accents on individual beats for complex patterns.
Subdivisions & Swing
Choose between quarter, eighth, sixteenth, and triplet subdivisions. For eighth-note subdivisions, adjust the swing feel to add groove.
Visual Beat Ring
A visual beat indicator shows the current beat in the measure. Useful for silent practice or when you cannot hear the click.
Tempo Presets
