      Music died here last spring, or rather, it was killed by members of the school committee who ignored

the importance of music and drama as part of the highschool curriculum.

      The committee decided that teaching students how to take a standardized test is more important than

a curriculum in which students can explore their interests in the arts as well as academics. Because the

school system is running out of funding, it needs to make sure that students pass the mastery test or even

more money will be lost. If students fail the state standardized test, it is not the fault of drama and music

classes-they are failing because the "academic" classes are not sufficient.

     It is painful to think of how many students will be discouraged from singing, acting, and playing

instruments because school programs are no longer offered. Many families cannot afford private music

lessons, and many potential musicians and artists may not find their calling if they are not exposed to it in

school. The fact that the school committee thinks the arts are not worth the investment will certainly make

some students believe the arts are not worth their time or support and the cycle will continue.

      Teaching for a test does not shape students into complete, well-rounded people. It blocks the natural

sense to create and express feelings through art-there is more to life than the analytical thinking that math

and English provide. What happens after a test?Sure, a student might graduate, but they will have limited

knowledge-certainly not a good preparation for the real world.
