Creating music does not necessarily require the fine motor coordination of using traditional controllers.
Grader A: hit
Music creation without fine motor skills was established by 2009. Loop arrangement, step sequencing and drag-and-drop composition in GarageBand and similar tools need only a mouse.
Test: Routine availability: loop-based composition in software pre-installed on all new Macs from 2004.
Grader B: hit
Loop-based arranging and on-screen sequencing let users make music with a mouse, with no instrument technique. GarageBand's Apple Loops (2004) and Magic GarageBand (2008) are examples, as are step sequencers and DAWs generally. By 2009 music creation without fine motor coordination on a traditional controller was common.
Test: Test: common music-creation methods need no instrument technique by 2009. Loop and sequencer software was standard (GarageBand on every Mac from 2004; DAWs widespread in music production).
