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

'contemporary sound' is the definition.
(sound on a mobile phone)

'musical cycle has style' is the wordplay.
'musical cycle has' becomes 'ring' (I can't justify this - if you can you should believe this answer much more).
'style' becomes 'tone' (tone is a kind of style).
'ring'+'tone'='RINGTONE'

'and' is the link.

Can you help me to learn more?

(Other definitions for ringtone that I've seen before include "Sound of modern life" , "Sound heard when someone telephones" , "Sound made by a mobile phone" , "announcement of caller" , "Nitrogen (anag.)" .)
