Practice room
Online metronome and practice tools
This is a new site of in-browser tools for people who are practicing: tempo, click, song length, transposition, pitch, a practice loop, a drone, and a microphone tuner. Nothing here downloads or streams songs. The metronome click is Web Audio in your browser, not a hardware studio metronome.
Tap tempo
Metronome
Tempo
Online metronome
BPM, meter, accent on beat one, and optional eighth or sixteenth clicks.
Tap tempo
Tap a pulse, read rounded and raw BPM, then send the tempo to the metronome.
Practice loop
Count-in, play bars, rest, and repeats against the session click.
Song length calculator
Bars, BPM, and meter become minutes and seconds. 32 bars at 120 in 4/4 last 1:04.
Bars and time
The inverse: a duration and a tempo become a bar count, with rounding explained.
Delay time calculator
Milliseconds from BPM for straight, dotted, and triplet note values.
Polyrhythm metronome
Two pulses from 2 to 8. 3 against 2 shares one cycle at the session tempo.
Pitch
Chromatic tuner
Microphone to nearest note, hertz, and cents. Nothing is uploaded.
Drone tone
A sine reference on a chosen note. A4 starts at 440 Hz.
Note frequency calculator
Note plus octave to hertz, or hertz back to the nearest note and cents. A4 is 440 Hz.
Interval calculator
Two pitches, the semitone count, and the name. C to G is a perfect fifth.
Interval ear training
Hear two tones and name m2, M2, m3, M3, P4, P5, or P8.
Transpose chords and capo
Shift simple names such as C, G, Am, and F♯, or read shapes as if capo N.
Capo chart
Open C, G, Am, F, D, Em, A, and E shapes against capo 0 through 7.
Circle of fifths
A study chart for key signatures. It is not a fortune-telling wheel.

Guides
What BPM is
How this site uses beats per minute, and how tap tempo averages a pulse.
6/8 and 3/4 in these tools
Why 6/8 uses two dotted-quarter beats, not six eighths, for duration.
A440 and MIDI 69
The default reference, other concert pitches, and the frequency formula.
Why these pages do not host audio files
Practice tools only. No tracks, no remixes, and no downloads of other people’s songs.
Delay time in milliseconds
How this site turns BPM into delay times, including dotted and triplet values.
Capo and transpose
Why capo 2 on a C shape sounds as D, and when to use the transpose page instead.
How the practice loop counts
Count-in, play, rest, and what the practice log stores.
About this site — a new practice-tool service, not an archive of old downloads.
Common questions
What pitch standard do the frequency tools use?
A4 is 440 Hz unless you set another reference, such as 432 Hz or 442 Hz. MIDI note 69 is A4. The formula is written on the note frequency page.
How does 6/8 work here?
Duration and the metronome treat 6/8 as two dotted-quarter beats in each bar. BPM is the pulse you would conduct, not six eighth notes. The guide on 6/8 and 3/4 spells this out.
Why are there no MP3 files or song downloads?
This site is a set of practice tools. It does not host, stream, or offer downloads of recordings. The click you hear is generated in the browser.
Does anything I type leave the browser?
Tempo, bars, and notes stay in this browser. There is no account and no upload. The metronome does not send audio to a server.
Can I tune from these pages?
The chromatic tuner listens in this tab after you allow the microphone. The note-frequency page is a calculator. Room acoustics and a hardware tuner still matter on stage.
Which note names does the site use?
English letter names: C, D, E, F, G, A, and B. Accidentals are written with ♯ and ♭. In some countries the note B is written H; this site uses B.
