Bard & Skills

[ECDubz]

Hey guys I started up my bard last week and so far i'm up to lvl 33 and have noticed a lot of missed notes when playing some higher level songs. Should i take time out of my day to sit in town or spend skill points to raise my instrument skills higher or is this something that gets fixed with a higher Dexterity? I'm thinking of leaving my bard afk while using specific songs to raise the instrument skills but obviously it won't be full AFK because of the server kickout timer. Let me know what you guys think.
