About

Atril is a project by Eduardo Keser, tuba player and brass instrument repairer in Yerba Buena, Tucumán (Argentina). After years of repairing trumpets, horns, trombones and tubas, and playing in brass ensembles, we built the tools we always wanted: a tuner that also explains why a note is out of tune.

Every tool runs inside your browser: the microphone sound is never recorded or sent anywhere.

We also publish sheet music for brass ensembles at EBK Brass. If the tools help you, you can buy us a coffee.
