Sound of tribe heading for glory (5)
I believe the answer is:
clang
'sound' is the definition.
(I know that clang is a more specific form of sound)
'tribe heading for glory' is the wordplay.
'tribe' becomes 'clan' (synonyms).
'heading for' says to take the initial letters.
The initial letter of 'glory' is 'g'.
'clan'+'g'='CLANG'
'of' is the link.
(Other definitions for clang that I've seen before include "heavy metal sound" , "Resounding effect" , "Resounding metallic noise" , "Jangle" , "Noise from crane" .)
