Musician offering support with hymns, regularly (6)
I believe the answer is:
'musician' is the definition.
(Brahms is an example)
'support with hymns regularly' is the wordplay.
'support' becomes 'bra' (a support for the breasts).
'with' means one lot of letters go next to another.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The alternating letters of 'hymns' are 'hms'.
'offering' is the link.
(Other definitions for brahms that I've seen before include "19th century German composer, known for Lullaby" , "Composer of a well-known lullaby published in 1868" , "He scored" , "Composer (associated with Liszt?)" , "drunk?" .)
