Question

Mention about the extension of music

Answer 1

In music, an extension is a set of musical notes that lie outside the standard range ortessitura.

StaffEdit

A note that lies outside the lines of a musical staff is an extension of the staff. The note will lie on a ledger line. Middle C for example is an extension note on both treble and bass clefs, however is not outside the grand staff. Soprano C and Deep C lie two ledger lines above treble and below bass respectively (as well as the grand staff).

InstrumentsEdit

An instrumental extension is a range of playable notes outside the normal range of the instrument. A baritone horn, if played by a skillful player, can be played an octave above the normal range. Since this isn't standard, these notes would be an extension. See also:Crook (music). With the bowed string instruments, lower pitches than the standard range are sometimes used throughscordatura in which the lowest string is tuned down a note or two. The double bass sometimes uses a C extension extending the range of the E string downwards to C. SomeBösendorfer pianos have extra keys, extending the range several notes lower than a standard 88-key piano.
