Hey All

I am suddenly stuck with what seems to be the first hard obstacle

The D Major Chord I'm at the guitar fundamentals 1 50% of it done with no major issues I even mastered the Ode to Joy on all 6 strings playing the same song on high stings and low string with almost no diffciculties but after that, the fundamentals 1, gets back to chords, I learnt earlier simple chords, and now Em, which is fine and then D major or just D.

I can't make it sound good the tone is not clean it is 2 days I keep on trying no way to make it sound good looks like my fingers are too tick even though I think to have small hand but not very long fingers, I still doubt that this is something to do with fingers probably takes time to shape it good with good tone?

Thanks
