Each row is one key signature. The first column shows how many sharps or flats it has, the second lists exactly which accidentals they are in their standard order, and the last two columns give the major key and the relative minor that share that signature. Sharps are always added in the order F♯ C♯ G♯ D♯ A♯ E♯ B♯ — “Father Charles Goes Down And Ends Battle” — and flats in the reverse order, B♭ E♭ A♭ D♭ G♭ C♭ F♭.
For a sharp key, the last sharp in the signature sits one semitone below the tonic — so if the final sharp is F♯, the key is G major. For a flat key with two or more flats, the second-to-last flat names the key — B♭ and E♭ means B♭ major. F major (one flat) and C major (none) are the two to memorize outright.
A chart tells you the answers; practice makes them stick. Test yourself with the key signature quiz, drill relationships on the circle of fifths game, or fill in the blank circle worksheet from memory.
There are 15 major key signatures — from 7 flats through no accidentals (C major) to 7 sharps — and 15 relative minors, 30 keys in all. Because of enharmonic spellings there are 12 distinct pitch collections.
Sharps are added in the order F♯ C♯ G♯ D♯ A♯ E♯ B♯ ("Father Charles Goes Down And Ends Battle"); flats are the same names in reverse: B♭ E♭ A♭ D♭ G♭ C♭ F♭.
Find a key in the left column: the chart lists how many sharps or flats it has, exactly which accidentals they are (in order), and its relative minor, which shares the identical signature.
