The project seeks to make sound recordings of the jazz band display which will be the centrepiece of the Laigh Room when St Cecilia's Hall reopens in April 2017.  The display is of instruments which form the regular members of a 1920s "trad" jazz band.  Although hearing the sound of instruments is of great importance to the visitor offer in St Cecilia's Hall, and many individual instruments have been recorded, to date all of the recordings have been of single objects rather than a group of instruments playing together.  The jazz band will therefore be the first ensemble recorded as part of the interpretation offer.  The instruments will be played by University of Edinburgh students (led by a PhD student who also plays professionally as an early-jazz drummer), allowing the students to experience original instruments of the period and to see first-hand how they have changed over the past 90 years.  One or two short pieces will be recorded.  The record engineering and mixing will be carried out by University music technology students.  The recording will take place in the Reid Concert Hall, making use of the in situ studio facilities.  Each instrument will be recorded onto its own track.  The project will produce pieces of fully-mixed music that can be downloaded from the website (in which the ensemble is balanced as a whole), and be included on the museum app.  By recording in this manner it would be possible, in future, to develop a program in which listeners could "boost" any of the instruments and hear that part at a higher volume than all of the others.
