Hmm, good advice, but even on a regular size guitar, I find it tricky to hit some of those tight chord shapes too, because my hands are small but my fingers are a bit fat. For example, an open A chord, I can’t use three fingers to fret it or I’ll have the strings buzzing. I have to use 2 or even just 1 finger to get that. So if the fretboard was smaller, yes, I could do stretches easier, but then I’d be screwed playing the tighter chords...
Plus, I’ve been playing piano so long now most of it is second nature. On guitar I have to sit and think things through, and that is such a pain once you are used to being able to just play by ear on another instrument.
Try dropping the tuning to D and it requires less pressure from your fingers. If you have an electronic tuner then tune 1 & 6 string {top & bottom} to D. The easiest way is to place a Capo on the second fret and tune it to standard E then remove the Capo. Much easier on the fingers and if you are wanting to play with other players just pop it back on at the second fret. That’s how I’ve always tuned mine for years. A Capo also a real good way to get those way up the neck chord sounds by moving it up the neck LOL 12-15 basic chords will have you playing most songs unless you are in a top band. Even Pink Floyds Brain Damage can be played starting in D. On real hard to play chords as long as the sound is true experiment with your finger placement and you might find an easier way for you to do it.
