• Recognisable tunes, played to a reasonable standard, must be played throughout the attempt by a band/group of not less than four persons.
• Apart from pauses lasting no more than 30 seconds between tunes, play must be continuous.
• Standard instruments, of the type that would normally be used in a band or orchestra, must be used. No ‘self-playing’ instruments, such as electric keyboards, may play solos at any time during the attempt.
• Each piece of music must last at least two minutes.
• No piece of music may be repeated in performance within four hours. A play list of all the tunes performed must be maintained.
• If any member of the band/group retires, the end of their participation must be recorded immediately in the log book.
• If the number of persons in the band/group falls below four, the attempt is ended.
• No individual who was not present at the beginning of the attempt may participate at any time in the proceedings.
• A break of 15 minutes must be taken after every eight hours from the beginning of the event. The person attempting the record must take all toilet breaks during this period.

Delays or breaks owing to unforeseen circumstances, such as injury or severe weather conditions (in the case of outdoor concerts), will be judged on an individual basis.
