Male in charge introducing US blues, for example (5)
I believe the answer is:
music
'blues for example' is the definition.
(blues is a kind of music)
'male in charge introducing us' is the wordplay.
'male' becomes 'm' (common abbreviation).
'in charge' becomes 'ic'.
'introducing' is an insertion indicator (some letters introduced or inserted into others).
'm'+'ic'='mic'
'mic' placed around 'us' is 'MUSIC'.
(Other definitions for music that I've seen before include "Melodious sounds" , "melodies" , "Composed sounds" , "Aural art" , "Aural entertainment" .)
