A happy man is using music to get his message across to his audience.
"Once upon a time, there was a musically gifted communicator who really touched his listeners."
The notion of musicality
Ability to create, perform or perceive music; sometimes also used about other arts, for example literature. The best presentations have an element of musicality, meaning that the tone of voice, pauses, intonation and accentuation match the meaning of the words and the purpose and intentionality of the presentation – and the presentation overall has a musical character. Musicality in communication is like a carrier wave that flows into and around us, affecting us in a way that is normally the reserve of music. A melodic presentation that is conceived, written and delivered with musical flair is more easily absorbed.
