Seek the pedal application of the piano music Liuyang River.

At present, there is no Liuyang River spectrum with pedals on the Internet, but generally speaking, the pedals should be changed in every bar (that is, the pedals should be released once and then stepped on), and the pedals should be changed where the chords are changed. If the reverberation of strings is long, it will be noisy if there are too many sounds, so the frequency of changing pedals should be increased appropriately, one at a time.
