"As part of his early work for McCulloch, Gauld designed a set of eight music room panels, which, like those designed for the Guthries, featured tall slender maidens playing a variety of musical instruments in pastoral surroundings. Significantly, however, where Gauld's work for the Guthries is often in treatment very close to his paintings of the period, panels designed for McCulloch are classic examples of the mosaic principle. The outline of the figures and each important part of the composition is drawn in the leadlines and given its own rich colour, while the paintwork is reduced to an absolute minimum. Alltogether Gauld produced at least eight separate designs for this series and they are without a doubt among his finest achievements in stained glass."
