Hi, My name is Darren and I myself only started about 6 weeks ago after joining a year ago and then having a long break through illness, (& 25 years too late).

I am not at my best yet but, I was told a couple of weeks ago, pick two of the chords that you struggle with the most and for 5 to 10 minutes change slowly between them, but when your fingers are placed on top of the strings, press hard for 10 to 15 seconds then change and repeat. It has improved my chord changing considerably. One other thing, only do two chords together at a time. It may seem to be a little monotonous but it did help me.

I hope that it works for you as well.

Take care,

Darren.
