A chord is built by stacking thirds, so each chord tone uses its own letter name (root, third, fifth and so on). That is why F♯ major is spelled F♯ – A♯ – C♯ and not F♯ – B♭ – C♯. The A♯ and the B♭ are the same key on a piano, but only A♯ is a third above F♯. Every tool here follows this rule, including double flats where theory requires them (C diminished 7th is C – E♭ – G♭ – B♭♭).
The rules come from standard music theory references, including the free textbook Open Music Theory. Automated tests check the spelling of every root and chord type here, plus the scale and chords of every major and minor key.
