Overview

A CRAM event. Includes Alda::EventList.

An Alda::EventContainer containing an Alda::Cram can be created using event list sugar. See Alda::EventList#method_missing.

The duration of a cram event can be specified just like that of an Alda::Note.

Alda::Score.new do
  piano_ c3 t4 { c2 d4 e f }; g2
end
