The structure row shows information regarding the different sections of a song or piece.
For example, a song might contain a verse, chorus and middle 8 and these would be shown in the structure row. Often a chart will not show the absolute structure of the commercial recording, rather the chord progressions of the individual sections.
Here is an example:
Structural symbols can also be placed in the structure row. This most often applies in classical music where repeating passages, 1st time bars and codas are often used. Here are a few of the symbols that can be seen.
Repeat Signs – Enclose a passage that is to be played more than once. If there is no left repeat sign, the right repeat sign sends the performer back to the start of the piece or the nearest double bar.
– Volta brackets (1st and 2nd endings or 1st and 2nd time bars) Denote that a repeated passage is to be played in different ways on different playings.
Coda – Indicates a forward jump in the song to its ending passage, marked with the same sign. Only used after playing through a D.S. al coda or D.C. al coda.
Segno – Indicates where to jump to from the instruction dal segno
D.S. – Dal Segno – Indicates to jump to the point in the music where the Segno sign appears.
D.C. – Da Capo – Return to the beginning.
The structure row can also be personalized to show any interesting points in the music that you might want to find again quickly.
