Songometry

YOUR MUSIC TOOLKIT Songometry brings 29 practical tools into one focused workspace for musicians, songwriters, guitarists, composers and producers. TEMPO & RHYTHM Practise with an audio-clocked metronome, tap a tempo, convert BPM to milliseconds and calculate delay or reverb timing. Convert bars to time, plan tempo changes and calculate sample time-stretch ratios. CHORDS, KEYS & GUITAR Transpose chord progressions, calculate capo positions and compare likely keys. Explore chord progressions, identify chords from notes, browse scales and modes, navigate the Circle of Fifths and analyse progressions with Roman numerals. Check how a song fits a vocal range. AUDIO & PRODUCTION Tune one note at a time with the microphone tuner and reference tones. Analyse an audio file locally for tempo and key estimates. Convert frequency and note values, calculate pitch-related playback ratios and estimate audio file sizes. SONGWRITING & RELEASE PLANNING Calculate song duration, build a section timeline and follow a release metadata checklist. Model royalty and streaming revenue, publishing splits and release break-even targets with clear assumptions. Core tools work offline and no account is required. Audio analysis happens on your device. Tempo, key and revenue estimates are references to check against your music and actual circumstances.
