Some words sound very good to me when they are combined. For example, the sport "ping pong", the cartoon character "Mickey Mouse", and the phrase "busy bee" sound better than "ping lock", "Mickey Eagle" and "busy whale".
I have written down a sentence below.
(ex) "Ping pong", "Mickey Mouse" and "busy bee" have harmonious or pleasant phonetic combinations.
In this context, can I use the phrase "harmonious or pleasant phonetic combinations" as an alternative for either "sound very good" or "pleasant-sounding? Does it make sense? Thanks.
