What note formats are accepted?

You can enter a single note like C4, F#3, Bb5, or Db2. For chords, type the root and quality like Cmaj, F#m, G7, Bbdim, or Asus2. Octave numbers are optional for chord roots.

What intervals are available?

All standard intervals from Unison (0 semitones) through Octave (12) and beyond up to two octaves (24 semitones). You can also type a custom semitone count between -24 and 24.

How are enharmonic notes handled?

The tool uses sharps by default (e.g. C# rather than Db). When transposing down or working with flat-key chords, the enharmonic flat spelling is also shown.

What solfege system is used?

Fixed-Do solfege is used (C=Do, D=Re, E=Mi, F=Fa, G=Sol, A=La, B=Si). Altered notes get the closest chromatic syllable.

Can I transpose a whole chord at once?

Yes. Enter a chord symbol like Gmaj7 or Bb9 and every constituent note will be transposed, showing the new chord name along with individual note results.
