何為inverted pedal point?

It is a pedal point at the top instead of in the bass line
(and often is the highest part.) Mozart included numerous inverted pedals in his works, particularly in the solo parts of his concertos.

In tonal music, a pedal point' (also pedal tone, pedal note, organ point, or just pedal) is a sustained tone, typically in the bass, during which at least one foreign, i.e., dissonant harmony is sounded in the other parts. Pedal points are often found near the end of fugues and other polyphonic compositions. Pedal points are usually on either the tonic or the dominant tones. The pedal tone is considered a chord tone in the original harmony, then a nonchord tone during the intervening dissonant harmonies, and then a chord tone again when the harmony resolves. A dissonant pedal point may go against all harmonies present during its duration, being almost more like an added tone than a nonchord tone, or pedal points may serve as atonal pitch centers.

The term comes from the organ for its ability to sustain a note indefinitely and the tendency for such notes to be played on a pedal division.

A double pedal is two pedal tones played simultaneously.

An internal pedal is a pedal that is similar to the inverted pedal, except that it is played in the middle register between the bass and the upper voices.
