The DLSU-D Brass Band is composed of a dynamic group of instrumentalists and band players. Since 1996, the band blows its harmony in various institutional activities and special functions within and off the campus. The members’ instruments have likewise brought esteem and laurels to the university.

The name of the band was derived from the Brass Instrument, a class of musical instruments made of brass or other metal, including trumpets, bugles, trombones, and horns. Orchestral brass instruments are derived from signaling instruments that in their natural or valve less form produce a directionally focused range of tones from the harmonic series by over blowing to as high as the 16th harmonic. They are powerful and efficient generators, and produce tones of great depth and resonance.

In the symphony orchestra the brass instruments are the French horn, trumpet, trombone, and tuba. In the brass band they comprise (in descending order of pitch) the cornet, flügelhorn, tenor horn, B flat baritone, euphonium, trombone, and bombardon (bass tuba).
