Dear Sir / Mam,

I have started practicing the chords G, A and D. When I am playing the G major chords, all the strings are played; for A major chord only 5 strings are played and for D major chord 4 strings are played.

My question is : When I am strumming the D major chord, all the 4 strings needs to be played while doing both the downstroke and upstroke; for A major chord - all the 5 strings needs to be played while doing both the downstroke and upstroke?

I am having difficulty playing the upstroke accurately and correctly when switching from G to A (playing from 6 strings to 5 strings when doing the downstroke and upstroke) or from G to D (playing from 6 strings to 4 strings doing both downstroke and upstroke).

Please advise. Thank you.
