Responding to a post about a test question for second-grade students, which assumed they knew the words “commission” and “Mozart,” this parent replied:

My second-grader defined “commission” without needing the
multiple choice prompts this morning, but her school has a really
strong music program.

She credited her music teacher for having
taught her the term–which was done in the context of an annual
all-school field trip to a local Symphony Orchestra concert. (This
is not district-wide; our PTA fundraising pays for the cost of the
buses necessary to take all the kids. I don’t know of another
public school in the district or in the area that has all of its
kids at the concert every year; most take only one or two grades,
if they participate at all.)

Before they go to the concert, our music teacher gives the kids the elementary-school equivalent of a pre-concert lecture–which is to say, it takes place over a few
weeks and isn’t a lecture, but they come away with much of the same
information.

My daughter has also played violin since she was 4,
and her public school has a fabulous strings program that she’s
been in since kindergarten, also thanks to our fabulous and amazing
music teacher (who, it might be noted, belongs to the union and
runs the entire strings program during her free periods).

Our school is also blessed with amazing parents, and several of them
attend each and every orchestra rehearsal to help the kids tune
their instruments and set up music and stands. And in the spirit of
full disclosure, my daughter has a musicologist for a mother.

Do I think most second-grade students could define this term? Probably
not, especially with so many schools cutting music and arts
programs. Unfortunately, putting terms like this on a test will
likely have the effect of extending vocabulary lessons and cutting
into time that would otherwise be used for music or art or
