This week I get to do a piano recording for an artist I have worked with before. She is a very gifted pianist and the sessions go rather well. I am planning to use a Decca Tree with three Audio-Technica 4050's in bidirectional mode. I have used this setup with this performer before and had excellent results. The recording is being done in a 600 seat auditorium with variable acoustics provided by dropping down large curtains to damp the hall. The last time we did the recording my notes show we used 50% coverage. The piano is a German Steinway that has been a joy to record in the past. Any other suggestions? Thanks in advance.
