I'm playing a Scherzo by Daniel van Goens (Op. 12, No.2). It says I should play a G (space above the top line in Treble Cleff) as a harmonic (has a 0 on top of it). I have not been able to find it. Is it an actual harmonic or do I have to shift from my previous note (G second from bottom line in Treble Cleff as a harmonic) all the way up there?

It is at the end of the finger board on the A string,

Is there any other one closer to my previous note?

I'm sorry but that harmonic turned out to be too high and a little flat. I found another one that was right on the G string but I'm afraid it was down in almost the same place but on the G string.

Thanks for the help. I think that the music had a mistake and that it really was not supposed to be a harmonic.

As a natural harmonic, that pitch is impossible to play on either the A or D string. It's the eighth natural harmonic on the G string and the twelfth natural harmonic on the C string.

You can play it as an artificial harmonic on the D string by stopping the first G with your left-hand thumb and simultaneously lightly touching your left-hand ring finger on the node a perfect fourth higher.

Thanks for the reply, I may try that. But I might just play it normally, thats how I've been practicing it.
