beautiful, emperor Shun's music
韶 centers on aesthetic beauty, especially in music or performance. The specific reference to Emperor Shun's music is a historical application of that idea of beautiful, harmonious sound.
韶 combines 音 (sound) with 召, which likely contributes the sound and may suggest calling or summoning. Together they express beautiful, harmonious music.
Sound 音 is summoned 召 in a beautiful way: imagine a conductor calling forth a beautiful melody.
For ショウ, picture a beautiful show of music: show -> ショウ, and the sound 音 is the star of the show.
