Editing Flat (music) (section)

==Other notation and usage==

* Historically, raising a double flat to a single flat would be notated using a natural and flat sign ([[♮♭]]) or vice-versa ([[♭♮]]) instead of using only a flat sign (♭). In modern notation the leading natural sign is often omitted. The combination ♮♭ can be also written when changing a sharp to flat.{{Citation needed|date=March 2025}}
