The layering comes quickly in this video from Ryan Kunkleman. A button is pushed and the harmonica disappears off-screen. We hear a few notes, and we expect the playing to complete a phrase, for the player to pause for a breath. This doesn’t occur. Instead, before the original phrase ever ends another one is layered atop it. Looping has been enacted. There will be no pause for breath for the nearly 13 minutes of this piece. What there will be is a steady accumulation and movement between the held tones of the harmonica, chords giving way to phrases giving way to chords, little moments occasionally peeking (and peaking) through the sonorous clouds.
The tools, in addition to the harmonica and microphone, are a recent piece of software called Cheat Codes (github.com/dndrks), running on a Norns, an open-source sound computer from Monome (monome.org).
This is the latest video I’ve added to my YouTube playlist of recommended live performances of ambient music. Video first posted at Kunkelman’s YouTube channel, under the moniker esc.
