Types of key signatures
There are four types of key signatures in Dorico SE, which can all be input, moved, and deleted in
the same ways.
The four types are:
● Major
● Minor
● Open key, or atonal
● No key signature (for specic instruments, such as horn or percussion)
Major/Minor key signatures
The key signature for a major key appears the same as the key signature for its relative minor,
and vice versa. For example, B♭ major has two ats in its key signature. This is the same number
of
ats as for G minor, which is the relative minor key to B♭ major. The difference is that music in
G minor usually has sharpened Fs, as the seventh degree of the scale is raised in minor keys.
Therefore, if you input an F♯/G♭ after a G minor key signature, Dorico SE prefers to spell it as F♯ in
most cases, in order to follow the convention of harmonic minor keys.

Open key signature
Although open, or atonal, key signatures appear the same as C major or A minor key signatures
because none shows any accidentals, open key signatures behave differently.
