Having a hard time keeping the a string muted while plucking on the g sting.
I will usually do one of:
- rest my thumb on it
- mute with the pinky of my plucking hand
- palm mute it
- mute it occasionally with a spare fretting finger
but muting is hard and is a skill sort of developed over time.
Resting your thumb on it is the easiest - getting used to moving your thumbrest for convenience is a good thing to do.
I float my thumb, so it naturally lands on the D string and also mutes the A. E, and B strings when I pluck the G string. Obviously if you anchor your thumb on the pickup at all times (as many bassists do), this would not work, so I guess you’d have to mute the A string with your fretting hand.
How do you currently mute the D string when you play the G string?
My preferred position is to have my thumb rest two strings lower than the string I’m playing. If I’m playing the G string, I’ll rest my thumb on the A string. My pluck across the G string will land on the D string and mute it. An upper part of my thumb is also muting the E string.
If I have to play the D string from that position I won’t move my thumb just for that.
If I have to play the A string I’ll move my thumb up to the E string or the pickup depending on what else I’m going to play next. I try to pick thumb positions that either minimize moving around or get me through a difficult phrase. I’m OK reaching for the G string if I know I’m going to be back on A anyway and won’t have a muting problem.
It’s a little bit like choosing fretting fingering, presetting positions to allow unwinding the next phrase gracefully.
@howard gets to give you more options than I have in my ability. I don’t have the other techniques mastered yet so I’m still making this one work the best I can.
+1 here!
My best advice for getting better at additional muting techniques: play with a pick
If it’s a quick move to the g, i’ll rest my thumb on the a to mute both the e and a. If i’ll be playing on the g for more than a few notes, i’ll probably use floating thumb muting.
