The Lindenhurst music department has always strived for excellence in music education and the musical development of every student. Elementary school students begin exploring music through the use of simple movement and Orff instruments, such as xylophones and drums, in their music classes. The exploration continues with singing and playing recorders. As students get older, they can participate in performing groups such as band, chorus and orchestra. Lindenhurst music students are also encouraged to further their musical development by competing in NYSSMA festivals every year. Outstanding students participate in districtwide select performing groups, such as the All-Lindy Chorus, Band and Orchestra.

Music education does not stop when the student reaches the secondary level. Besides continuing classroom music training, young musicians can perform in the Chorus, Middle School Band and Orchestra and other select performing groups such as the Chamber Orchestra, the Jazz Band and the Middle School Select Chorus. These groups perform at a high level and have been recognized with numerous awards and honors in and out of the district.

Lindenhurst High School offers the opportunity for students to further develop their musical abilities. The performing group students can perform in Concert Band, Concert Choir, High School Chorus and Orchestra, and several select performing groups such as Jazz Band; Marching Band; Odyssey, a mixed vocal ensemble; Songbirds, a female vocal ensemble and the String Chamber ensemble. Students can study music simply to broaden their education or prepare for musical studies on a collegiate and conservatory level. The High School produces an annual musical that allows students to showcase their talent.

The completion of the new state-of-the-art electronic music lab, which includes iMacs and 88-key fully weighted keyboards at 20 student stations, allows high school students to take classes such as Class Guitar I and II, Class Piano I, Class Piano II and Electronic Music.
