Without getting into a lot of acoustic arcana about how and why, the natural trumpet—the instrument’s version 1.0, just a coiled brass tube without valves—sounds earthier than the modern version, with a smaller range. To compensate, players up through Bach and Handel’s day developed a brilliant florid technique (it’s all in the lips and lungs), an art being revived by the Seattle Trumpet Consort. They’ll demonstrate with a concert this afternoon to celebrate the release of their CD. In their repertory is not just music from the baroque era, but later works too: Wagner, Britten, even a newly-commissioned piece, plus a music-box-like divertimento by the boy Mozart, with flutes and timpani, that you won’t hear anywhere else. Trinity Parish Church, 609 Eighth Ave., www.seattletrumpetconsort.com. $25. 2 p.m. GAVIN BORCHERT Sun., May 11, 2 p.m., 2008
