3RD TIER:
Five male musicians 'gonin bayashi' (五人囃子):

*Small drum (太鼓 'taiko')-seated.
*Large drum (大鼓 'ōtsuzumi')-standing.
*Hand drum (小鼓 'kotsuzumi')-standing.
*Flute (笛/横笛 'fue' or 'yokobue')-seated.
*Singer (謡い方 'utaikata'), holding a folding fan-standing.

Each region and family has their own way of arranging the dolls (choosing what paraphernalia to include), but there is a loose set of rules I'll briefly mention.

Due to limited space and money, many families have smaller sets that may include only the main dolls.

In Kyōto the mebina sits to the left, in Kanto the mebina is typically on the right of the obina.
