The music room acquired its name more or less by accident. It is not especially well-suited for performing music (the bare walls result in a distinctly 'bathroom' acoustic), nor is it particularly politic to play music there rather than anywhere else. The room has no form of sound-proofing, and as always in the Tower sound tends to travel up and down the stairwell as if down a speaking-tube — an argument in the kitchen is quite capable of carrying all the way up to the workroom and the ears of anyone else present, a fact worth bearing in mind by the short-tempered.

The music room is simply the room in which the musical instruments are mostly stored, and hence in which they are usually played.

The only mild rarity is the large organ-like instrument that stands near the door to the spare bedroom, carefully positioned in the angle between the end window and the back wall. This is in fact a harmonium — the 'organ pipes' are fakes, simply intended to make the instrument look grander. Rather than supplying an additional bass line, the player's feet are required to perform the more prosaic rôle of pedalling at a steady rate in order to supply the necessary wind. On the other hand, it does avoid the necessity of employing a small boy to pump the organ bellows!

Other instruments include a small upright piano which stands against the partition wall and carries so clearly into the bedroom next door that it is quite impossible to play it when that room is occupied, two violins in cases, a trumpet, two trombones — one with valves, one without — a mandolin, a guitar and a whole set of recorders in the most common sizes. These are accompanied by a number of music-stands in varying stages of dilapidation, and a roll-fronted cabinet containing a vast quantity of sheet music along with various printed volumes arranged on a shelf above.

Between the windows hang various pencil sketches, illustrating characters from various pieces of fiction. Otherwise, there is little furniture. A large and squashy sofa and a brightly-coloured rug hung on the back wall bear witness to an attempt to dampen down the reverberations somewhat, and several of the spindly wicker-seated chairs are currently arranged in a group around a couple of music-stands, though the music has been put away.
