I have just started Grade 2 so looked ahead in Justin’s lessons and come across two possible explanations, either a palm mute, module 8 Or percussive strum in module 14.
I have found a Tab, see below, and it shows a column of x’s after two chords, and the legend says mute strings. So I am thinking you play the two chords then palm mute, which gives you the stop, am I along the fight lines.
Thanks for the clarification Toby @TheMadman_tobyjenner
I appreciate that you are not familiar with the song but it has.a very catchy intro riff and the melody follows through the rest of the song. I am going to give it a go it doesn’t look more complicated than Justin’s riffs in Grade 1, although I think the timing is going to be the difficult bit.
