glissando on strings, lute
琵 centers on a stringed musical instrument, specifically a lute, and the glissando technique of sliding across its strings. The two meanings are closely linked: the instrument and a characteristic way of playing it.
琵 is a phono-semantic compound: the top 玨 (two pieces of jade) suggests a stringed instrument often adorned with jade, while the bottom 比 (compare) likely contributes the sound. It is part of the word 琵琶 (biwa), a traditional Japanese lute.
The top 玨 looks like two jade ornaments on a lute, and the bottom 比 suggests comparing the smooth sliding sounds. Picture a lute with jade inlays, and your fingers gliding across the strings.
For ビ, imagine a bee landing on the strings of a lute and making a buzzing glissando: bee -> ビ.
