New Tri-M Chapter forming at Tesoro HS!

Student run Giving Bach club to transition to Tri-M this summer!

UPDATED: 07/13/2019 -- The popular Giving Bach club will be transitioning this summer to form a NEW TRI-M Chapter in time for the upcoming school year (2019-2020). With the assistance of the Music Directors, the club will be formally applying to have a chapter of the national Tri-M Honor Society at Tesoro HS. This is amazing news, and a terrific opportunity for Tesoro HS music students to become involved in a national association that can offer many benefits.

What is Tri-M you are wondering? Read on!

  • The Tri-M® Music Honor Society is NAfME’s international honor society for middle/junior-high and high school students. This National Association for Music Education (NAfME) program recognizes students for their academic and musical achievements, rewards them for their accomplishments and service activities, and inspires other students to excel at music and leadership.

  • Tri-M® offers many different advantages: not only does it create community within your music department, it also benefits your school and community as well.

  • Each school has its own chapter, which is run by the students but supervised by an advisor or sponsor, usually a school Director. 

  • Tri-M welcomes student musicians in grades 6 through 12. Currently, there are over 2,100 chapters in all 50 states, involving more than 84,000 students! Besides shining a bright light on their school’s music programs, these future leaders contribute more than 750,000 service hours in their local communities.

Additionally, for students that join Tri-M, there is access to scholarship Funds. Tri-M provides scholarships and awards that are designed to motivate and reward those chapters and individuals who perform their Tri-M® duties and their community service with distinction.

The Tesoro Music Program is extremely excited to offer this new opportunity to all Music Students in the program!!
