50 music teachers gathered at Broadview Middle School in Danbury on Tuesday during a professional development day to learn how to get students even more excited about music class. The day of instruction was part of a grant to bring Little Kids Rock into the Danbury schools. A few teachers from other districts were also invited to participate.  Over the past year, Little Kids Rock has trained and equipped six Danbury schools music teachers with $24,000 worth of guitars, keyboards, drums and technology, and recently provided an additional $80,000 worth of instruments.
