Day 28: Bar Lines & Repeat Signs
Apart from the regular bar line, a variety of other bar lines are useful to indicate specific moments in the music.
The final bar line
is written at the last measure, indicating that the music ends here.
The double bar line
indicates that there is a significant change in the music, such as the beginning of a new section.
Music that is written inside the begin repeat sign
(or open repeat
) and end repeat sign
(or close repeat
) is repeated (it’s played twice). Notice the dots accompanying the lines:
See companion course: Audio Example 28.1
But when a section of music is repeated from the very beginning, the first repeat sign is normally left out. In this early Minuet
by the young Mozart, the first four measures are repeated.
See companion course: Audio Example 28.2
Upon repeating, a new ending is sometimes called for. This is notated with the alternate ending
lines. The brackets numbered 1 and 2 below are alternate endings - once the music is repeated (as instructed by the repeat signs), the 2nd
ending replaces the 1st
.
In our companion course, you will find an interesting example named Audio Example 28.3: On the first playing, the melody is played until the first ending (measure 5). At this point it is repeated from the note C
(measure 2) and the 1st
ending is replaced by the 2nd
ending.
Other Repeats
1. Da Capo al Fine
The da capo al fine
marking is an instruction for the musician to go back to the beginning and play till the measure marked fine
. The term da capo al fine
is Italian for from the beginning to the end.
It’s often abbreviated simply as D.C al fine.
In Audio Example 28.4, the 8 measures are played in full and then the first 4 measures are played again. The music ends at the word fine.
2. Dal Segno al Fine
The dal segno al fine
(Italian for from the sign to the end) is related to the da capo
but instead of repeating from the very beginning, it is an instruction to repeat from the measure marked with this sign:
The term dal segno al fine
is often shortened into D.S. al fine.
In Audio Example 28.5, the melody is 16 measures long. Once the first 12 have been played, measures 5 to 8 are played again (because measure 5 is where the segno is). The melody finishes at the word fine.
In short, the measures are played in this order: 1 to 12 as written, and 5 to 8 again.
3. Da Capo al Coda
Da Capo al Coda
(from the beginning to the ending) instructs the musician to go back to the beginning and play until the measure labeled al coda
–Italian for to the ending.
Once there, the musician skips to the measure labeled coda
–
a musical term for ending.
The coda
itself is marked with this symbol:
In Audio Example 28.6, the melody is 16 measures long. It’s first played until the term
D.C. al coda
(measure 8). From here, the music goes back to the beginning until the term
al coda
(measure 4). From here, the melody goes to the
coda
sign (measure 9) and is played to the end (measure 12).
In short, the measures are played in this order: 1 to 8, 1 to 4, 9 to 12.
