Answer: For example, start and end repeat marks often occur in the middle of a bar, without interrupting the rhythm of the music. At the start of a system, there is no barline between the key signature and the first note or rest, but there may be a "start repeat" mark in that position.
The correct option is D. Clef
What is a clef in music?
A musical-notation symbol at the beginning of a music staff, a clef indicates the pitch of the notes on the staff. Clefs were originally letters, identifying letter-named pitches, that were added to one or more of the staff's lines (thus providing a "key" to their identity).
What is G clef meaning?
[English] A symbol located at the beginning of a staff to indicate the pitches of the notes placed on the lines and spaces of the staff. The G clef is so named because the symbol is a stylized letter "G" that encircles the line of the staff, indicating where the "G" above middle C (G4 or g1) is located.
How many musical clefs are there?
four clefs
Each of these clefs has a different name based on the tessitura for which it is best suited. In modern music, only four clefs are used regularly: treble clef, bass clef, alto clef, and tenor clef. Of these, the treble and bass clefs are by far the most common.
