Cantāmus is a new singing rehearsal tool developed by Barcelona-based AI company Voctro Labs. It allows choir singers to practice their part with vocal practice tracks synchronized to the score. Cantāmus was developed by Voctro Labs within the TROMPA project, a Research and Innovation Project funded by the European Commission. Due to the success of this project, the tool has already been used by many other organizations and choirs including Messies Participatiu, CantoríaMargarets Choir (Canada), Chorus Soranus (Denmark), Coral Sant Medir and Igualada Gospel Choir.

Following excellent feedback and increasing demand, Cantāmus is now being launched publicly. It offers a paid ensemble membership, for vocal ensembles and choirs of any size, from a small vocal quartet or a mid-size choir, to large virtual choirs or participatory events. You can find more details about pricing and how to purchase on the Cantāmus website.
