Felt piano

Spectral Pocketing

Felt piano involves placing a layer of soft cloth or felt between an upright piano's hammers and strings before tracking. Damping the physical impact softens the acoustic attack and suppresses bright, brittle high-frequency transients, creating an attenuated, dark instrumental tone.

How the songs in the archive use it

In Billie Eilish's lovely, muted upright piano hammers yield a dark timbre that carves out acoustic room for whispery vocal tracks. Lewis Capaldi's Someone You Loved uses felt damping tracked through stereo AKG C414 microphones to turn chord patterns into muted, percussive cushions.

How to do it in Logic Pro

Damp an acoustic piano's hammers with a layer of cloth to soften transients and capture a warm, intimate tone. Use this technique for delicate cinematic scoring, ambient music, or mellow ballad arrangements.

  1. Open the top lid or remove the front panel of an upright piano to expose the hammers and strings.
  2. Suspend a thin strip of soft wool felt across the strings directly between the hammers and the wire courses.
  3. Position a stereo pair of microphones close to the hammers to emphasize the soft, mechanical felt textures.
  4. Perform with a light, controlled touch to prevent striking through the felt cushioning.

A general method with Logic Pro's own plug-ins. Control names are checked against Apple's manual; the values are starting points, so adjust them by ear.
