I remember the first time I heard a harmonic, it was like I’d witnessed magic - and when I realised how it was achieved, I was blown away… so simple. However, the technique to achieving a clear and strong tone is like a dark art, but not at all unachievable given knowledge of the appropriate technique.
Listening to Llobet’s version of “El Testamento de Amelia“ for the first time was incredible… how were those harmonic arpeggios created? Again, so simple with practise and dedication.
I remember witnessing one of Gary Ryan’s masterclasses at the London Guitar Festival, King’s Place, a couple of years ago; he encouraged the students to stop looking at the fingerboard whilst playing, most were amazed that this was even possible and astounded that their playing even improved (due to setting themselves free from the constraints of observing their fingers and technique probably), but he was very honest and admitted that even he has to look at the placement of his fingers when playing artificial harmonics - encouraging for us mortals!
The video looks at both natural and artificial harmonics and one extra technique for good measure!
