Why does a B flat clarinet read a different note?

It sounds a major 2nd lower than written. To sound concert C, its part says D, a tone higher.

What does an alto sax read for concert C?

A, a major 6th higher. Concert E flat major is written in C major for alto sax.

Are the transposed chords spelled correctly?

Yes. Each chord moves by an exact interval, so in D flat major you get B flat minor, not A sharp minor.

What happens to text in my chord chart?

Anything that is not a chord symbol is left as it was, and the tool lists any chord-like words it did not change.

About this tool

Paste or type chords, choose the key they are in and the key you want, and every chord symbol is moved and spelled in the new key; bar lines, words and other text stay where they are. The second tab works out written and concert pitch for transposing instruments: clarinet and trumpet in B flat, clarinet in A, alto and baritone saxophone in E flat, horn in F and tenor saxophone, with the key signature the player reads.

Tips

A B flat instrument reads a tone higher than it sounds, so concert C is written D.
Capo players: transpose down by the capo fret to find the shapes to play.
