Double sharp, in music notation, refers to a note that is raised by two half steps. This can be represented by the symbol "x" or "##" placed before the note. In IPA phonetic transcription, the pronunciation of "double sharp" is /ˈdʌb.l̩ ʃɑrp/. The first syllable, "dub," rhymes with "club," while the second syllable, "ble," rhymes with "table." The pronunciation of "sharp" is represented by the IPA symbol /ʃɑrp/, which sounds like "shar-p."
Double sharp is a musical term used to describe a symbol that indicates one step or note higher in pitch than what is conventionally written. It is denoted by placing two sharp signs (♯♯) before a note. Traditionally, sharp raises a pitch by a semitone, but double sharp raises a pitch by two semitones. Essentially, it acts as an intensified version of the ordinary sharp.
In music notation, the double sharp symbol is sometimes used when there is a need to temporarily raise a note that is already sharp. For instance, if a note is written as E♯ and then needs to be raised by another whole step, it would instead be notated as E double sharp (E♯♯). Therefore, the double sharp is primarily employed to modify or alter a previously sharp note, enhancing its pitch.
When a double sharp is encountered in a musical composition, it indicates a higher tonal quality compared to a single sharp. The double sharp has a significant impact on the melodic and harmonic structure of the music, often creating tension or dissonance. Its use is more common in advanced classical music, particularly compositions written in keys that naturally contain a lot of sharps.
Overall, double sharp serves as a valuable tool in music notation, allowing composers and performers to notate and perform highly chromatic music with accuracy and precision.
The word "double sharp" has its etymology rooted in the tradition of Western classical music and theory. In music notation, a sharp sign (#) placed before a note raises its pitch by a half step. However, in certain musical contexts, a note might require an additional half step raise in pitch. To denote this, the double sharp symbol (×) is used.
Etymologically, the term "sharp" can be traced back to the Old English word "scearp" or "scearpe", meaning "cutting" or "piercing". This word was later assimilated into the Old High German as "scarf", signifying "sharp". Over time, "sharp" came to be associated with raising the pitch of a note.
The prefix "double" in the term "double sharp" simply indicates an added level of "sharpness" or a further increase in pitch.
