A bit of didgeridoo at the end of dance song (6)
I believe the answer is:
ballad
'song' is the definition.
(ballad is a kind of song)
'a bit of didgeridoo at the end of dance' is the wordplay.
'bit of' says to take the initial letters.
'at the end of' means one lot of letters go next to another (some letters go at the end of others).
'dance' becomes 'ball' (ball is a kind of dance).
The first letter of 'didgeridoo' is 'd'.
'a'+'d'='ad'
'ad' put after 'ball' is 'BALLAD'.
(Other definitions for ballad that I've seen before include "Narrative poem or song" , "Narrative song with a recurrent refrain" , "A simple or old song" , "Song that tells a story" , "Form of verse" .)
