Studio Overview

The trombone studio at Colorado State University is a challenging, fulfilling place to study the art of musicianship through the trombone. The studio members are a close-knit group of students who are supportive of each other, enjoy making music together and love playing the trombone! Whether pursuing a performance, music education, music therapy, composition degree, or music minor, students are guided to reach their goals by Dr. Drew Leslie.

Dr. Leslie is passionate about the trombone and music education and brings a wide variety of performing and teaching experience to Colorado State University. His teaching emphasizes great sound, intonation, and musicianship at the highest level and students are encouraged to perform on the trombone with these three things foremost in their minds. Lessons are structured around building a solid foundation in all of the fundamental areas of playing, along with an in-depth study of etudes, solos, orchestral/band excerpts, and jazz.

Studio size is approximately sixteen, with a maximum of four graduate students. A weekly studio class is held where students get the opportunity to perform in front of their peers and receive constructive feedback on their development. There is also the Colorado State University Trombone Choir, an all-trombone ensemble that meets once a week. This group specializes in 4-16-part arrangements and original compositions written specifically for this unique type of ensemble. All styles and time periods of music are covered, and different types of trombones (tenor, bass, alto, etc.) are utilized.

All students are actively encouraged to form trombone quartets and brass quintets to develop their chamber music skills and the ability to make a world-class blended group sound.

The studio owns various instruments for check-out by students. These include an alto trombone, several bass trombones and a contrabass trombone. Students are able to gain experience on these instruments without having to worry about financial burden of purchasing them.

Studio members take part in many other ensembles across campus including the CSU Marching Band, Wind Symphony/Symphonic Bands, Symphony Orchestra, and Jazz Ensembles/Combos.

Alumni of the trombone studio are found throughout the nation making positive contributions to the field of music. Graduates hold positions as music educators, performers, and music therapists (just to name a few!)

Scholarships and assistantships are available and are awarded on merit.
