Store description excerpt
Ulzii is an instrument for fingertip meditation, inspired by Mongolian throat-singing (khoomei) and the tradition of drone music. At its core is continuous tuning, free from the twelve equal-tempered Western scale. Two ribbons let you freely set the pitch of two voices; touching the central pad shapes the color of that voice's resonance (like a vowel) depending on where you touch. The name "Ulzii" comes from the endless knot found in traditional Mongolian ornamentation — echoing this app's core idea of an unbroken, continuous drone. - Continuous tuning ribbons: note names are just reference points — slide your finger to tune freely to anything in between - Central pad: touch position shapes vocal resonance (overtone color); an optional VOWELS overlay shows common vowel positions - Three playing modes: UNISON (locked to voice I), FOLLOW (a delayed echo of voice I), and ORBIT (an autonomous, ever-moving layer) - Sleep / meditation timer: 3–30 minutes, gently fading out at a slower tempo — ideal for bedtime or meditation Headphones are recommended. This app does not collect or transmit any personal data or performance data.
