Cassp,
No you are not too old. What type of music will you be playing? We have classical guitars with wide necks and soft nylon strings – Acoustic guitars which have round holes, they are the most difficult to finger because of the gauge of the strings, they are normally heavier because of the desired volume. Electric like guitars Gibson, Fender and the cheaper models would be considered the easiest to finger.
Fact --- The most difficult learning on a guitar is to learn to play melody combined with chords, very much like a piano player. I would suggest learning chords, not just the fingering but everything about them. How they follow each other (Progressions) how they are constructed (What notes make up a chord) everything you can find get into.
Most the past 50 people I have taught I direct to chords combined with chord understanding. Note learning is great it will give you the entire picture but leave that for later. The chord understanding I am talking about will keep the doors open for future self-learning.
You’re going on a great journey Cassp, there is nothing as personal as a guitar. My last thought is about the people on this forum – boy, they are up and ready to help, after your 2389 posts it’s time you sat back and enjoyed.
Let us know how you are doing with the guitar.
