'useful to composers' is the definition.
I can't judge whether this defines the answer.

'the many points' is the wordplay.
'many' becomes 'M' (Roman numeral for a thousand).
'points' becomes 'Es' (two compass points).
'the'+'m'+'es'='THEMES'

Can you help me to learn more?

(Other definitions for themes that I've seen before include "Subjects or repeated musical pieces" , "'Subjects, topics (6)'" , "Motifs, subjects" , "Subjects or repeated melodies" , "Topics, ideas, motifs" .)
