It may not seem like the average engineer's hobby, but for more than 60 students in the Cockrell School of Engineering, playing an instrument in the Engineering Chamber Orchestra (EChO) is how they spend their free time – when they have it.

EChO is a student organization that places musically-inclined engineering students into ensembles with other EChO members. Pianists, vocalists, brass, string, woodwind and percussion players make up the 70-person orchestra, said oboist Sarah Pederson, the group's president and undergraduate in biomedical engineering.

Pederson said nearly 80 percent of EChO members are engineering students, with about half of the orchestra being first- and second-year students, one-third upperclassmen undergrads, one-sixth graduate students, and even a professor from the Computer Science Department.

"I am enjoying being able to further (EChO's) growth as a student organization and being part of this community of musicians within the engineering school," said Pederson, who played in her high school's wind ensemble and full symphony orchestra, as well as the UT Symphony Band for three semesters.

EChO recently hosted its Winter Concert Series Dec. 4-5, which was a culmination of everything the ensembles had been working on throughout the semester. Performances were held in the Quadrangle Room of the Texas Union and donations were accepted at the door in support of Save the Music Foundation.
