Input
Single note: C4 · Chord: Cmaj, F#m7, Bbdim
Result
Enter a note or chord and click Transpose
Solfege (Fixed-Do): C=Do · C#/Db=Di/Ra · D=Re · D#/Eb=Ri/Me · E=Mi · F=Fa · F#/Gb=Fi/Se · G=Sol · G#/Ab=Si/Le · A=La · A#/Bb=Li/Te · B=Ti
Summary
This transposition tool lets you shift any note or chord up or down by a named interval or raw semitone count. Results appear in standard scientific notation (e.g. D4, F#5) alongside fixed-Do solfege syllables. Enharmonic equivalents are shown where relevant, making it useful for composers, arrangers, and students working across different keys and instruments.
How it works
- Enter a note (e.g. C4, F#3) or chord (e.g. Cmaj, G7, Bbm) in the input field.
- Select an interval by name (e.g. Major 3rd) or type semitone count directly.
- Choose the direction: up or down.
- The transposed note or every chord tone appears instantly in scientific notation.
- Solfege equivalents (Do, Re, Mi…) are shown alongside each result.
- Copy the result with one click.
Use cases
- Transpose a melody or chord chart to a new key without a physical capo.
- Learn interval relationships by watching how each note shifts.
- Convert sheet music written for one instrument to another transposing instrument.
- Check enharmonic equivalents when the transposed note has a flat or sharp.
- Practice sight-singing by generating solfege for any transposed passage.
- Quickly find the relative pitch of a note after modulation in a composition.
