Visualization of brass players’ warm up by infrared thermography
Matthias Bertsch

During the warm up of trumpet players, face muscle contractions with increased blood flow result in a higher temperature of the overlying skin. This effect can be visualized and quantified by infrared-thermography. The analysis demonstrates that the main facial muscle activity during warm up is restricted to only a few muscle groups (M.orbicularis oris, M.depressor anguli oris). The “trumpeter’s muscle” (M.buccinator) proved to be of minor importance. Less trained players expressed a more inhomogenous thermographic pattern compared to well-trained musicians. Infrared thermography could become a useful tool for documentation of musicians playing technique
