The loudspeaker position that changes a bass note
A bass note can change when a speaker or chair moves, because room modes and wall reflections alter what reaches the listener. The cure depends on which path caused the change.

About the author
Music listener and amateur bassist
I live in Manchester, work in a public library and play bass with friends when everyone's schedules allow it.

I am more interested in how a piece feels in a room than in proving ownership of the right equipment.
Room for Listening collects essays on musical attention, arrangements, albums and domestic listening habits. I write about small discoveries: an overlooked bass line, a pause that changes a song, a sequence of tracks that makes sense only when heard together. I avoid treating enjoyment as a test that listeners can fail.
My listening room is also a living room, with books, laundry and a chair that has survived several attempts at tasteful rearrangement. Outside music I enjoy cooking, old films and conversations that begin with one song and end somewhere entirely different.

I sat down to hear an album and discovered I was also checking a message, reading a headline and deciding whether a photograph deserved a response. The album became the sound accompanying several other activities.
