Gabrieli - Ego Sum, Qui Sum for Brass Choir by Cherry Classics Music published on 2025-05-10T04:57:55Z Ego Sum, Qui Sum (C. 29) by Giovanni Gabrieli is from his 1597 Sacrae Symphoniae written for an 8-part antiphonal choir traditional sung at Easter Sunday Matins. David Mathie has transcribed and edited this gorgeous work for an 8-part Antiphonal Brass Choir with each choir being 2 Trumpets in B-flat and 2 Trombones. It is perfect for advanced-intermediate performers as it has moderate demands with range and technique and would be a great work to introduce younger less experienced players to Gabrieli's double choir works.
