Some guitarists face a similar problem when playing seated, needing to raise the instrument into proper paying position while keeping it on the leg. There are collapsible adjustable foot rests designed for this purpose. They are inexpensive and highly portable.
Google `guitar foot rest' to see lots of these devices, and figure out what features are likely to be best for you. Your local music store will undoubtably stock a few. _______________________________________________ post: [email protected] unsubscribe or set options at https://pegasus.memphis.edu/cgi-bin/mailman/options/horn/archive%40jab.org
