Claps and MIDI notes count as taps

Every input adds its own delay: keyboards, trackpads, microphones, Bluetooth audio. Calibrate each one you use. You hear 4 clicks, then tap or clap along with the next 12.
With metronomeCount-in, then tap along with the click.
Free tempoTap without a click; the tempo and barlines are worked out afterwards, using your meter.
FTwo voices: F or the left half of the pad plays the low voice, and so do MIDI notes below middle C.

Changes apply instantly to the last take.

GridTaps are written in this note value or longer. The triplet key allows triplets.
SimplicityHigher prefers plainer rhythms when a tap sits between two readings.
Tempo correctionSteady fits one tempo and offset to your taps; Follow drift also tracks rushing and dragging.
Note lengthsAs held reads key/press release, so gaps become rests.
Longest noteLonger gaps are written as rests. With two voices, No limit still stops at one beat.
Ignore double tapsTaps closer together than this count as one, per voice.
½× 2×Fixes a tempo read at double or half speed.
◀ ▶Move the barlines by a beat if the downbeat is in the wrong place.
Timing chartTop row: your taps against the click · bottom row: where they were written · click a tap to ignore it

Anyone with the link can listen, clap it back and get a score. Nothing is uploaded: the link holds the rhythm.

The notes stay hidden until they have tapped it once: rhythm dictation.

    Turn a rhythm in your head into notation
    
    
    Quick start. Three steps, no account, nothing to install.
    
    
      
      
    1. Tempo. Tap the beat or type a tempo, and choose a meter.
      2. 
      
    2. Rhythm. Press space, then tap the rhythm on the space bar, the mouse or a touch screen, clap it into your microphone, or play it on a MIDI pad or keyboard.

    3. Notation. Read it, play it back, and export it.

    Claptoscore writes what you meant rather than exactly what you played. It measures your latency, snaps each beat to the simplest subdivision that fits, follows you when you rush or drag, and ignores accidental double taps.
    
    
    What it writes
    
    
      
      
    • Quarter, eighth and sixteenth notes, dotted values, ties and rests
      • 
      
    • Eighth-note triplets in simple meters, and 6/8, 9/8 and 12/8 compound meters
      • 
      
    • Two voices on a percussion staff: F for the low voice, J or space for the high voice
      • 
      
    • Free tempo takes without a metronome, with the tempo and barlines worked out afterwards
      • 
    
    
    
    Practise solfège and rhythm reading
    
    
    Clap a rhythm from your solfège book or sight-reading exercise along with the click, then compare what Claptoscore wrote with the page. If they differ, the timing chart shows exactly which note you rushed or dragged. It works for rhythm dictation too: listen, tap back what you heard, and check it.
    
    
    Share a rhythm as a link
    
    
    Press Share under the notation to get a link to the written rhythm. Whoever opens it can listen to it, clap it back and get a score for every note, or open it here to change it. Tick Hide the notes and the link becomes a rhythm dictation: they hear it, tap it back, and only then see the notes. The link holds the rhythm itself, so nothing is uploaded. How teachers use it.
    
    
    Counting under the notes
    
    
    Switch Count to Numbers to see 1 e & a under every note, or to Kodály for ta, ti-ti and tika-tika. It works in the lessons too.
    
    
    Playing flamenco or salsa? Clap along with the compás and clave patterns: soleá, bulerías, son clave, bossa nova and more, each with accented clicks and scored exercises.
    
    
    New to reading rhythms? Work through the rhythm reading lessons: ten short lessons from quarter notes to 6/8, where you clap each exercise and get note-by-note feedback.
    
    
    Tips for a clean result
    
    
      
      
    • Calibrate once per input. Keyboards, Bluetooth headphones and microphones each add their own delay.
      • 
      
    • Use headphones when clapping, so the metronome click does not reach the microphone.
      • 
      
    • If a beat comes out too busy, raise Simplicity; if a real sixteenth is missing, lower it.
      • 
      
    • Hold the key for the length of the note and switch Note lengths to As held to get rests from the gaps.
