2.2.4 Combining notes into chords
Music Glossary: chord
We saw earlier how notes can be combined into chords by indicating they are simultaneous by enclosing them in double angle brackets. However, the normal way of indicating a chord is to surround the pitches with single angle brackets. Note that all the notes in a chord must have the same duration, and that the duration is placed after the closing bracket.
\relative { r4 <c'' e g> <c f a>2 }
Think of chords as almost equivalent to single notes: almost everything you can attach to a single note can be attached to a chord, and everything must go outside the angle brackets. For example, you can combine markings like beams and ties with chords. They must be placed outside the angle brackets.
\relative { r4 <c'' e g>~ <c f a>2 | <c e g>8[ <c f a> <c e g> <c f a>] <c e g>8\>[ <c f a> <c f a> <c e g>]\! | r4 <c e g>8.\p <c f a>16( <c e g>4-. <c f a>) | }
