The fermata is placed above a note and allows the performer to hold that note as long as they wish. In old musical notation the effect of the could extend across the bar line, as shown in the example below. Further dots may be placed after the first one in which case each dot adds half the time value of the previous dot. The rhythm dot is placed to the right of a note or rest and extends the length of that note by half its value. In the example below the E can be tied to the F flat because, despite a different spelling in the notation, these notes are at the same pitch. It is possible to tie two notes of different names, so long as they are of the same pitch. The result is a single note whose length is the sum of the two tied notes. The tie is a curved line placed above or below two notes of the same pitch. There are signs which extend the length of notes or rests. In printed music the flags of two or more successive notes will be joined within each beat of the bar.Ģ.2 Extending the value of a note or rest The time signature is expressed as a fraction of the semibreve, for example 4/4, 2/4. In printed music the time signature comes immediately after the initial key signature. Within the bar the notes and rests must add up to the bar length indicated by the “Time Signature” at the beginning of the piece. A bar is the space on the stave between two bar lines. The different notes are listed in the table below, along with their equivalent rests and time value. This, however, does not have an absolute value, but depends upon the tempo indication at the beginning of the piece (Allegro, Adagio, etc.) (1)įor each note there is a corresponding rest of equal value. This unit of measurement is called the Semibreve (or Whole Note in the USA). Obviously, even for the duration of sounds it is indispensable to have a unit of measurement, just as it is for length (the metre) and weight (the gram) etc.
