I've owned guitars for years but never really given them the time and attention they deserve. My current abilities reflect this. However I'm determined to up the game and subsequent to obtaining a nice new one I've been putting some proper time in if only to refresh and polish the noodlings I've accumulated over the years, learn some scales and in general become more familiar with the feel of the instrument.
I'm taking the matter quite seriously. Historically I've gravitated towards very small picks as I find they flap about less and are more precise when I'm adopting my favoured playing technique which is a classical (I think) style whereby I hold the pick between thumb and index finger to strike the low notes while using the other three fingers to pluck the higher-pitched strings nakedly, in a sort-of arpeggiated manner, if that makes sense.
As a newbie I have some challenges I'm seeking to conquer. The first is to accurately strike the string I want to with the plectrum without brushing the adjacent ones. The second is damping but that's probably a subject for a different topic.
Do any of you seasoned players have any advice on the size of plectrum and the manner in which it's held? Years ago I knew a guitarist who I sought advice from but was quite zealous about the size of pick and how it was grasped. He was also very insistent on playing from the elbow, locking the wrist and using the forearm like a turntable arm where the pick was the stylus. While his approach worked for him it feels a bit robotic and instinctively I want to get more expression from the wrist - but perhaps that's the pianist in me.
I have a bad habit of 'digging in' as opposed to brushing the strings when playing certain things and I'm trying to improve that.
I'm aware of my immediate shortcomings (I'm also sure more will turn up in due course) and happily doing my thing to overcome them but any guidance or insight into why one chooses a certain size/style of pick over another and any related tips on holding/using it, especially in terms of accuracy, would be welcome
