19
Project Concerns

• Social
• The Novisync introduces many children to music
  and the arts, which has been shown through a
  ten-year study, tracking more than 25,000
  students, to increase test scores 2.

20
Project Concerns

• Music study can help kids understand advanced
  mathematical concepts. Music involves ratios,
  fractions, proportions, and thinking in space and
  time 2.
