1 definition by Kaitlyn {oboe and alto sax}

A phrase used by band directors and musical instructors of most kinds. Typically, it is assumed that the phrase means you will only be trying the music "one more time", but generally the phrase becomes repeated, and one more time evolves into three or four.
Our band director shouted "One more time", but we knew that we would in fact do the entire show at least three more times before finally leaving practice.

*collective groan*
Get the One more time mug.
