Here are the key points made in the document:
- Music programs are not available in all schools, suggesting not a high percentage of schools have them.
- Music can help students in many aspects of life, but schools aren't investing in music programs.
- The document suggests all high schools should have elective music programs.
It does not provide specific statistics about what percentage of schools have music programs or the average cost of a music program. The main point is that music programs are lacking in many schools despite the benefits to students, and the document argues all high schools should offer elective music programs.
