Readily noticeable in performances are the "hard beats" used to indicate sections of the song. The "traditional method" consists of a pronounced strike by all singers every other beat. These may appear in the first or second line of a song, the end of a section, before the repetition of a song. A cluster of three hard beats (on consecutive beats) may be used at the end of a series of hard beats, while a few beats in the first line of a song indicate performer enthusiasm. In the "Hot Five" method five beats are used, with the first hard beat four beats before the second, after which the beats alternate.
