I have an upright piano that can only go straight against the wall, nowhere else to put it. It's way too heavy for me to move on my own temporarily, if I wanted it moved I'd have to get a professional in.

I'm also wanting to start playing with other instrumentalists - and this means I won't be able to see them! There isn't room for them to play along side, they would have to be sat directly behind me as I sit at the piano.

Ironically due to an inheritance from my dear grandma I could buy a grand, but I don't have room for it, not even a baby or boudoir one. If only....

If I'm lucky I might find instrumentalists who have a more suitable piano arrangements in their own home, but I'd like to be able to do it here as well.

Somebody suggested using a mirror so that I can see them reflected while I'm playing and we can pick up cues from each other etc. I don't know why, but I feel as though this wouldn't work and would feel disconnected. Have any of you done things this way and found it successful?

Organists often have to rely on mirrors to have a vague idea of what's happening.

So do you find it a satisfactory arrangement? I was hoping to achieve more than 'a vague idea what's happening' but create a real ensemble feeling.

Can any pianists playing with one or two instrumentalists comment?

Usually arrangements have been perfect but I've had a couple of rehearsals on an upright. We just had to listen much more closely. Some things... like cues to come in together are harder... but usually we use our breathing to bring us together anyway. I say don't let it stop you

I accompany a male voice choir and we rehearse every week in the choirmaster's lounge, where the piano is up against the end wall. I've tried just once with a mirror on top of the piano, and it did not work - just distracting. We manage pretty well by my 'sensing' his conducting and the singers dynamics, etc.. I think you will get plenty of satisfaction in your 'not ideal' situation, but, if your playing partners are happy enough, then just enjoy the music making.
