ACEMM Communications Team

Drue M. Bullington


Drue’s primary role at ACEMM is that of Secretary on the Executive Committee. His secondary role is head of the Communications Team. Working with this multi-talented, and highly skilled team of volunteers on a weekly basis to bring fresh new ideas to our community of avid supporters and creators of elemental music and movement opportunities is exciting and energizing!

Becky Burdett


Becky currently teaches grades K-4 at the Abington Heights School District. Her goal is for each student to be joyful in the act of making, expressing, and creating music.  Her classroom pedagogy blends together the elemental patterns and movement basis of Orff-Schulwerk with the vocabulary of patterns presented in the Kodály method; she is certified in both approaches. Becky believes that students can be capable musicians when allowed the guided freedom to explore all areas of musicianship.


She is an active member of several music education organizations: AOSA, PAOSA, PMEA and NAfME. Becky was the the Boutique Chair for the National AOSA Conference in 2016. Currently she serves the Philadelphia chapter as Vice-President.


She has served as a clinician for local and state PMEA professional development, local Orff chapters, and the National AOSA Conference. She has humbly been named the American Center for Elemental Music and Movement Roster of Excellence.

In addition to her active role as a school educator, Becky also accompanies both soloists and choirs. Becky conducts two of the youth choirs of the Choral Society of Northeast Pennsylvania. Summer teaching includes the Performing Arts Institute, and the Pocono Mountain Music Festival Camp.
