S.T.R.E.A.M. Project on Sound Waves

Second-grade students learn about sound vibrations and the role of horns in world history on Aug. 13 at St. Pius X School. S.T.R.E.A.M. coordinator Mike Sepulveda, enlisted Karl Kemm, a music professor at Del Mar College, who specializes in the French horn.

Kemm showed and demonstrated instruments used by shepherds in northern European countries as well as horns used by the Romans.
