Bathroom singing

Bathroom singing, also known as singing in the bathroom, singing in the bath, or singing in the shower, is a widespread phenomenon. Many people sing in the bathroom because the hard wall surfaces, often tiles or wooden panels, and lack of soft furnishings create an aurally pleasing acoustic environment.

Overview

The multiple reflections from walls enrich the sound of one's voice. Small dimensions and hard surfaces of a typical bathroom produce various kinds of standing waves, reverberation and echoes, giving the voice "fullness and depth."
This habit was reported by Ibn Khaldun in Chapter 1 of his Muqaddimah:

Usage

Some musicians have sought to take advantage of the unique acoustics of bathrooms. Jon Anderson of Yes had tiles installed in the studio to simulate the echo effect of one's vocals in a bathroom. Paul Simon wrote:
"Weird Al" Yankovic in 1979 recorded his first single, "My Bologna," in the bathroom across from the California Polytechnic State University student radio station where he was DJing at the time.
