Music Analysis Tools

BPM finder

Estimate song tempo from either uploaded audio or a counted beat span, with a tap-tempo assistant built right into the page for faster capture.

Key detector

Detect likely keys either from uploaded audio or from a manual set of notes so harmony work can start from the route that is easiest for you.

Camelot wheel / harmonic mixing tool

Translate between standard keys and Camelot wheel codes so you can plan smoother harmonic transitions by hand.

Tempo tapper

Turn a list of tap intervals into an average BPM and stability read, or capture the taps live from the built-in tap pad.

Beat grid calculator

Lay out bar downbeats from either a manual tempo or uploaded audio so edits, cue points, and timing notes line up faster.

Time signature detector

Read likely time signatures from accent groupings so unusual grooves become easier to label and communicate.

Chord detector

Name a chord from either uploaded audio or manual chord tones so you can work from the source material you actually have.

Chord progression finder

Generate usable chord progressions from a key, mode, and emotional lane so writing sessions start with real harmonic options.

Scale finder

Find scales that contain a chosen set of notes so you can map riffs, melodies, and progressions quickly.

Pitch detector

Convert a measured frequency into the nearest note, or upload a sustained sound and let the tool estimate the pitch from the audio itself.

Vocal range finder

Measure a singer’s usable range from their lowest and highest comfortable notes and compare it to common voice overlaps.

Note-to-frequency converter

Convert notes into exact frequencies so synth tuning, oscillator setup, and harmonic math stay precise.

Frequency-to-note converter

Convert a measured frequency into its nearest note name and cents deviation when you need a direct pitch label.

Semitone / pitch shift calculator

Translate semitone shifts into playback ratios, percent change, and resampled BPM so pitch moves are easier to plan.

Transposition calculator

Shift keys and simple chord progressions by semitone so you can re-key parts for singers, instruments, or DJ edits.

Capo calculator

Find practical capo positions and chord-shape families for a concert key so acoustic arrangements fall into easier hand positions.

Metronome

Generate beat intervals, subdivision timing, and count-in maps, then preview the metronome click right in the browser before you commit to the settings.

Tuner

Compare a measured or uploaded pitch against a target note, with reference-tone playback and instrument presets built into the page.

Interval finder

Name the musical interval between two notes and surface the semitone distance so arrangement and theory checks are faster.
