The opening guitar part of John Mayer's "Slow Dancing in a Burning Room" features a fair amount of vibrato. I'm trying to master this part, but I'm having difficulty with the first chord (C#m).
The way I was taught to vibrato is to apply the motion from the wrist. However, due to the thumb wrap for the C# (9th fret of the low E string), I find it very difficult to move my wrist correctly to achieve a pleasant-sounding vibrato. It seems to be alright for the G# (11th fret of the A string), but I'm getting almost no vibrato on the E (9th fret of the G string).
This video clearly shows how John does it. Can anyone provide tips for how I can play it more like he does? Thanks!
