Visualization of brass players warm up by infrared thermographyMatthias 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 trumpeters 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
