Yadah

Yadah is a Hebrew verb with a root meaning "to throw", or "the extended hand, to throw out the hand"; therefore, "to worship with extended hand". Eventually it also came to denote songs of praise—to lift up the voice in thanksgiving—to tell forth and confess his greatness (e.g., Psalms 43:4). II Chronicles 20:19-20 is the yadah type of praise. The antonym is to bemoan by wringing of the hands.

Lifting your hands is almost always equivalent to a Yadah (whether literally or figuratively), especially when listening to music. When you Yadah to music, you are worshiping the image of the creator/source of the music.
