In 2025, four stars of the horn world decided to do something new. iQ was born.
What is iQ?
✨ iQ is Interstellar Quartet
✨ iQ is a space between stars
✨ iQ is inspired by Olivier Messiaen’s call to natural beauty
✨ iQ is supernatural
✨ iQ is only just getting started
iQ expands what a horn quartet can be by commissioning new works, reimagining repertoire, and pushing technical and stylistic boundaries — while celebrating the instrument’s luscious sound, educating the next generation, and building community through performances, residencies, and summer intensives.
