It can.

The playing of musical instruments demonstrates how the body can do multiple different tasks at the same time.

Piano for instance. Bass keys, treble keys, foot pedals and then singing on top of all that.

Try an organ, with feet doing the lead, and two different accompaniment types on separate keyboards.
Total spastic at first, but we learn.

You know what - That's the best example I can think of.

I made Dean's List once upon a time at GA Southern. 10 As and one C.

The C was in Piano.

Playing piano is a sequence of events along the same process.

Try playing piano and strumming a guitar at the same time.
