Etude is a private-label house brand of Guitar Center, used primarily on entry-level band and orchestra instruments sold through the retailer's family of stores, including Musician's Friend, Music & Arts, and Woodwind & Brasswind. The line is aimed at beginners and school-program musicians, with pricing and build geared toward first-instrument buyers rather than advancing or professional players.

The catalog spans brass, woodwind, and orchestral strings, organized into numbered student series. Representative models include the ETR-100 and ETR-200 Bb student trumpets, the ETB-100 student trombone, the ECL-200 Bb student clarinet, the EFL-200 student flute, and the EAS-200 alto and ETS-200 tenor saxophones, along with student cellos and double basses. Instruments typically ship as outfits with a case and basic accessories, and the brand also markets care products such as valve, rotor, and slide oils.

Because Etude is a retailer-owned label rather than an independent maker, manufacturing is handled by contract factories and the brand does not maintain its own website, artist roster, or social-media presence. Coverage in player communities generally frames Etude as a budget option suitable for students and rental programs, with more serious players typically moving on to dedicated instrument makers.

Etude has 10 products cataloged on Equipboard, including Cellos, Alto Saxophones, and Trumpets.
