Definition
  1. Noun:
    • A musical notation symbol: A double sharp is a symbol used in musical notation. It consists of two sharp signs (♯♯ or 'x') placed before a note. This symbol instructs the performer to raise the pitch of that note by two semitones (a whole tone) from its natural pitch.
Usage and Examples
  • Noun:
    • The key signature has a double sharp on the F, making it sound like a G.
    • When you see a double sharp, remember to play the note two half-steps higher.
    • The composer used a double sharp to modulate to a distant key.
Advanced Usage
  • Enharmonic Equivalence: A note altered by a double sharp is often enharmonically equivalent to another natural note. For example, C double sharp (C♯♯) sounds the same as the note D.
    • In this passage, the A double sharp is functionally the same as B natural.
  • In Key Signatures: While rare, double sharps can appear in key signatures, particularly in highly complex tonal music.
    • The piece is written in G-sharp minor, which requires an F double sharp in its harmonic form.
Variants and Related Words
  • Sharp (n): A musical notation (♯) indicating a note should be raised by one semitone.
  • Flat (n): A musical notation (♭) indicating a note should be lowered by one semitone.
  • Double Flat (n): A musical notation (♭♭) indicating a note should be lowered by two semitones.
  • Natural (n): A musical notation (♮) that cancels a previous sharp or flat.
Synonyms
  • Raised by a whole tone: (Descriptive phrase, not a direct synonym)
  • Two-semitone increase: (Descriptive phrase)
Related Phrases and Contexts
  • "Cancel the double sharp": To return a note to its original pitch using a natural sign or another accidental.
    • In the next measure, you must cancel the double sharp with a natural sign.
  • "Spelled with a double sharp": Refers to how a note is written in the score for theoretical correctness, even if it sounds like another note.
    • The leading tone is spelled as a double sharp to maintain the integrity of the scale.
