Accidentals are symbols that are placed in front of notes to alter the pitch they represent. They are used in music notation to instruct performers to play a note sharp, flat, or natural. The accidental is placed before the note it affects and is usually followed by a natural, sharp, or flat sign.
The natural sign (♮) cancels a previous accidental. It’s also used as the sole accidental for intervals of a minor third or less. The flat sign (♭) drops a note by a semitone, and the sharp sign (♯) raises it by a semitone.

Key Takeaways About Accidentals in Music
- Definition: Accidentals alter the pitch of notes, instructing performers to play sharp, flat, or natural.
- Types: The natural (♮) cancels previous accidentals, the flat (♭) lowers pitch by a semitone, and the sharp (♯) raises pitch by a semitone.
- Duration: Accidentals usually last until the end of a measure unless otherwise instructed.
- Keys with No Accidentals: C major has no sharps or flats, making it simpler for beginners.
- Purpose: Composers use accidentals to modify key signatures, create harmonic effects, or emphasize sections in a piece.
Sometimes accidentals are added to notes to remind you which pitches to play. This often happens when the composer wants to use enharmonic scales (same notes, different names).
Do accidentals reset on every bar?
On modern staff paper, a natural sign cancels an accidental when the same note appears repeatedly in a bar. Diamond-shaped notes (without stems) can also achieve this. If there’s no natural sign after a double sharp, double flat, or similar, the composer or performer should continue using the accidental for that note.
Accidentals last until the end of a bar unless noted otherwise. If a composer wants an accidental to continue, they place a reminder in front of the note. The performer has one beat to correct before a natural sign cancels it.
The use of accidentals in music notation changes based on the composer’s or performer’s guidelines and the involvement of enharmonic scales.
Which major key has no accidentals?
C major is the simplest key in music, with no sharps or flats. This scale has only natural notes, making it ideal for beginners since it requires no extra learning. Other keys without accidentals also use only white or black piano keys, or include all flats or sharps.
Which major key has the most accidentals?
The G♯ major key has seven accidentals, making it the key with the most. Its major scale has eight sharp notes. When a note must be sharp, it’s written as G♯ instead of G.
Other keys with seven accidentals include B♭ major, F♯ major, E♯ major, and A♯ major.
When are accidentals applied?
Accidentals change a piece’s key. For example, a composer writing in G major uses sharps to raise note pitches for a brighter sound. Writing in D minor, they’d use flats to lower pitches, creating a darker tone.
Musicians might use accidentals for enharmonic scales or to correct errors. They’re also necessary when changing time signatures or clefs within a piece.
Accidentals emphasize specific sections of music, like the end of a piece. They appear on notes held through the bar line, usually lasting fewer than four beats. They may also instruct a performer to use a glissando effect.
What are the benefits of using accidentals in music, and do they apply to all octaves?
Accidentals remind performers which pitches should be sharp or flat, based on the key signature. They can also create fresh, exciting harmonic sounds when combined with other notes.
Accidentals usually apply to all octaves. However, sometimes a composer might use a different accidental for a specific octave. They’ll show this using an accidental sign with a number above or below it, indicating the octave. For instance, to raise a note in the third octave, they’d place an accidental sign with the number 3 under it.
