(general pause, or grosse pause), the words lunga pausa, or simply the word lunga, are sometimes written over a rest to show that there is to be a prolonged pause or rest in all parts.

44. The fermata or hold
over a note or chord indicates that the tone is to be prolonged, the duration of the prolongation depending upon the character of the music and the taste of the performer or conductor. It has already been noted that the hold over a bar was formerly used to designate the end of the composition, as the word fine is employed at present, but this usage has practically disappeared and the hold over the bar now usually indicates a short rest between two sections of a composition.
45. The sign 8va...... (an abbreviation of all'ottava, literally at the octave) above the staff, indicates that all tones are to be sounded an octave higher than the notes would indicate. When found below the staff the same sign serves to indicate that the tones are to be sounded an octave lower. The term 8va bassa has also this latter signification.

47. The sign Col 8 (coll'ottava—with the octave) shows that the tones an octave higher or lower are to be sounded with the tones indicated by the printed notes.
