Somehow stop dismal singer (10)

I believe the answer is:

psalmodist

I'm a little stuck... Click here to teach me more about this clue!

'singer' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I don't see?

'somehow stop dismal' is the wordplay.
'somehow' is an anagram indicator.
'stop'+'dismal'='stopdismal'
'stopdismal' is an anagram of 'PSALMODIST'.

Can you help me to learn more?
