Please check your schoolloop class webpage frequently, as I update them weekly.

I look forward to making music with all of you,

Mrs. Duffy

Helpful Links - Great resource for theory information, includes interactive lessons and games. Also has a staff paper generator. - Large sheet music inventory. Good place to purchase music for the District Solofest and The Lounge.

Mrs. Duffy's Bio

This is Mrs. Duffy's 8th year at Etiwanda and she is THRILLED to be teaching here! She previously taught band and choir in the high desert.

She received her Bachelor's degree in Music from UCR, her single subject music credential from Cal State San Bernardino and has just finished her Master's coursework at Cal State Los Angeles in their Three Summer Masters of Music in Choral Conducting program.

She has been singing and playing instruments her whole life, and knew at the age of 14 that she wanted to teach music. She enjoys eating, and can thus be well bribed with food. She also enjoys traveling (everywhere!) and organic gardening.

She is looking forward to another fabulous year at EHS!
