At the end of Tarantelle (and also at the end of the first presto), there is a chord with three normal notes and the fourth is an artificial harmonic. I know the harmonic works, because I tried it separately. Each time I play the chord, the fourth note, the harmonic, just won't work. It produces strange sounds (Edit : I checked the note, it is one octave lower than the desired sound), as if the chord's other notes' resonance disturbed the harmonic. And each time, I keep my hands still, and try the harmonic separately, it works. So is there a way to be able to play it with the chord or am I doing something wrong?
