F vibrato:
At 5:41 in this video, you can see Farid do it, though he is also playing with tremolo so it isn't the clearest aural example:

There's also a very clear instance at 4:04. There's a good one at 2:16 but the crowd is so loud you can barely hear it. Good visual though.
It's not something that can be notated or explained clearly. The main thing is that the motion comes from the hand/arm and not from the fingers—the
angle of your finger should stay the same. It is a wide, rapid vibrato, almost a shake. It occurs especially when it will be soon followed by the
sikah note.
As near as I can explain, it usually feels like it starts right on the note, goes above by about 1/4 tone, below by about 1/8 tone and vibrates about
as fast as possible. But it is a little different depending on the context—if it's a long note you can vibrate slower and more evenly. If it is
very quick it may be almost, but not quite, like playing an F# upper neighbor tone (just by sliding quickly rather than using a different finger).
These are somewhat subjective attempts to evaluate it though, I'm not sure how accurate it is. I learned by listening, watching and imitating. I
don't think one could get it from consciously following a description. |
