Classic Cantabile is a house brand of Musikhaus Kirstein, a music retailer based in Schongau, Bavaria, Germany. The line was developed to offer affordable instruments and accessories aimed primarily at beginners, students, and budget-conscious hobbyists, and is sold almost exclusively through Kirstein's own retail and online channels in Europe.

The catalog spans an unusually broad range for a single brand, including digital pianos and stage pianos, keyboards, classical and acoustic guitars, ukuleles, banjos, mandolins, violins, cellos, and double basses, as well as brass and woodwind instruments such as trumpets, trombones, saxophones, flutes, and recorders. The brand is also known for its plastic brass instruments under the MardiBrass name, along with harps, accordions, harmonicas, and percussion items for children.

Beyond instruments, Classic Cantabile produces a wide selection of accessories — music stands, music folders, instrument stands, gig bags, keyboard cases, and benches — that are commonly stocked alongside the instrument range. The brand's positioning emphasizes accessible price points and entry-level usability rather than professional or signature-artist gear.

Classic Cantabile has 3 products cataloged on Equipboard, including Acoustic & Acoustic-Electric Basses, Mini Guitar Amplifiers, and Beginner Kits.
