-If I wanted to find the key signature of D Major. First I find D on the sheet. Because we want to find D major, we will only use the major side, which is on the right. It is in the sharps section, because everything below C on the list has sharps (for major scales). C major has no sharps. G major has 1 sharp because it is 1 below C. D major has 2 sharps because it is 2 below C. So we know it has 2 sharps.
- To find out which 2 sharps, simply count down from the top of the list all major scales with sharps (any with flats you count from the bottom). It has 2 sharps so it has F sharp and C sharp. If the scale we were trying to find had one sharp it would be F sharp only. And if it had four sharps, it would have F, C, G and D sharp, because you count down from the top of the list.
- To find a minor scale (e.g. G minor). Find the note on the sheet, in this case it is G. We will use the right side of the sheet because the scale is minor. The scale A minor has no sharps or flats. The section above A concerns flats. D minor has 1 flat note, and G minor has 2 flat notes.
- To find the flat notes in a minor scale, count the notes from the bottom (to find sharps in a minor scale, count from the top). G minor has 2 flat notes, so we take the 2 notes counting up from the bottom. This would make the key signature B flat and E flat.
