Very nice, graffjamie!
I agree with you about no age limit
Our little one was very intently following my husband fingers as he is playing classical guitar since she was about 10 days old.
She also would react, when he would "miss" a cord ( on purpose) in a familiar melody.
And watching my husband play is her favourite activity.
I am so impressed that you were introducing classical guitar to your son as well! So inspiring!
Would you be able to share some practical tips? What would you do in a typical a few minutes "lesson". I am sure for him it is a fun play, but do you have some structure, where have you started first, do you show cords and tell their names, notes and show their names. Is he primary watching and listening or you are giving him some picking to try, and how dis you started it?
Anything else along the same lines... I am so glad that someone does it and very curious to hear back from you with some tips.
K to you!
