I have been playing piano for several years, but I never got a particular lesson on pedaling. I know the basics: for most romantic pieces, the point is to clean the pedal (with "clean", I mean raise and press again) at the moment where the chords change. For what I have heard, that is the key: release the pedal when harmony changes and press it back again. But then I started learning about how pedal is notated. Consider this example from Chopin's nocturne Op. 9 No. 1:
As far as I know, there are essentially two symbols here, the Ped and the star; where Ped means "press the pedal", and star means "release the pedal. If this is the case, then, in this example, the notation does not coincide with the description I learnt; there would be two options here (measure 2):
Method 1) Following the notation: Pedal is pressed in beat 1 and released in second half of beat 3, pressed back again in beat 4
Method 2) Release-press method: Pedal is pressed in beat 1 and released in beat 4, pressed back again just afterwards.
So is my interpretation of the notation wrong (i.e. is the notation describing the method 2)) or is the notation saying what method 1) says?
Hope this question makes sense, thanks in advance!
