Abstract: A modular apparatus having at least two connecting members substantially at right angles from each other for self-supported wielding of musical instruments. The modular apparatus is worn over at least one shoulder and around the back of the user's neck while it is detachably connected to a musical instrument, such as a violin. The musical instrument is detachably connected to the modular apparatus via a support attachment, support, strap and fastening mechanism. The plurality of members allows even distribution of pressure and tension throughout the upper body caused by supporting and playing the musical instrument.
