I have only been playing classical guitar for 6 months and am working on my posture and finding ideal ergonomics for playing.
90% of my playing has been bossa nova/jazz music, and I discovered in videos that Joao Gilberto always propped both feet up about a foot off the ground with a large stool.
I have a left foot pedal and find that raising one leg up is nice for playability but seems to disagree with my back more than elevating both legs. With both legs elevated I have the neck more parallel with the floor than (I assume) a classical player would advise.
I am looking into support cushions like dynarette to allow me to raise the neck of the guitar without having to hike one leg up way higher than the other, although this will force me to get over the psychological anxiety that using a support cushion is somehow weak or cheating, however foolish my reason knows that feeling to be.
My question is if anyone has experience with playing with support cushion vs. without and with boths legs raised vs. with one leg raised. My guess is that jazz and bossa and perhaps other styles that require more rapid chord changes and less complex and long melodies may be more conducive to the neck parallel to floor posture. It is the ideal posture for playability right now for me but I have a feeling I will have to learn a more traditional posture to reduce hunching over and have the ideal set up to play classical pieces.
Thanks for any knowledge and experiences
