Synonym discussion
Sense: noun/1
Close harmony is closest to 'tight harmony', which also suggests parts packed into a narrow pitch space. 'Four-part harmony' tells you how many vocal lines there are, but those four lines can still be either close or open. 'Open harmony' is the main contrast because its notes are spread farther apart.
