Dance and sing, somehow rising (9)
I believe the answer is:
ascending
'rising' is the definition.
('ascend' can be a synonym of 'rise')
'dance and sing somehow' is the wordplay.
'and' means one lot of letters go next to another (I've seen this in other clues).
'somehow' indicates anagramming the letters.
'dance' put after 'sing' is 'singdance'.
'singdance' with letters rearranged gives 'ASCENDING'.
(Other definitions for ascending that I've seen before include "Getting up" , "Going up" , "Rising" .)
