A wonderful graph which shows how strongly the sounds of the piano, strings, woodwind and brass instruments are associated with fruity smells, across smells of low, medium and high fruitiness.
From a recent study entitled ‘A Fruity Note: Crossmodal associations between odors and musical notes’.
The study also tests how strongly these instruments are associated with acrid, floral and spicy scents, in case you needed to know.
