Hi @MsJocko
That’s great advice and a superb mindset - adjusting your sights, pausing to reflect and recalibrating your practice and achieving the desired results. Bravo and kudos.
You mention that your third finger lags behind going from A to D.
Try this to see if it helps.
This exercise is designed to improve the ability to place all fingers on a chord simultaneously by actually doing the opposite – placing them one at a time, but in varying sequences. This will build finger independence which is essential for finger cooperation.
- Place each finger sequentially on to the strings to form the chosen chord in the orders 1, 2, 3 then 2, 3, 1 then 3, 2, 1.
- Do four repeats for each combination.
- Repeat but with the sequential placing reversed, now following the orders: 3, 2, 1 then 2, 1, 3 then 1, 3, 2.
- Finish by making four attempts to place all fingers simultaneously.
Perform this exercise with just the D major chord to begin. It will take a couple of minutes of your practice routine. After several days you should be seeing and feeling some improvement.
I hope that helps.
Please let us know if you try it and if it works for you.
Cheers
