Stepping into your stance automatically created a natural pivot of your shoulder horizon.
As you stepped back, your shoulder made a natural 45 degree angle adjustment. (Left Shoulder Forward, Right Shoulder Back)
Congratulations!
The natural angle created by stepping into your stance accustoms you to accept the weight transferred to your body, from the instrument to you.
You just created your Instrument Shelf.
The Instrument Shelf uses leverage to keep you balanced, which supports string playing motions.
Keep your shoulders loose and relaxed and your arms ready to float to comfortable playing position.
As your right foot steps back, your shoulder horizon pivots naturally.
Leverage is then achieved!
A well set-up Instrument Shelf is able to support the weight of the Violin and Viola, 100%.
