That can be said about any form of communication. Words on a page convey what words spoken can't always.
The right touch in the right way Can connect you more than any sound or word could ever hope to.
A painting can make me feel things a book can't make me understand. A performance or dance can show me something i can't hear or speak
It's different ways of experiencing experiences. What is communicated is not always the same between different subjects and objects. Even if they often do
But also to your point hearing music IS different from feeling music and different from creating it. I think music as a communication tool is fuzzy and not very good at communicating clearly. Powerfully i dont deny but not everyone can be affected the same way by the same music either so it's not a dependable form of communication.
And sometimes yes those feelings can be conveyed by other means.
But you seem like you might enjoy this song
Ren - Hi Ren (the music video is worth watching if you listen to this one)
