 Some vocal coaches have extensive formal training, such as a Bachelor of Music, a Master of Music, a Conservatory diploma, or degrees in related areas such as foreign languages or diplomas in human kinetics, posture techniques, or breathing methods.On the other hand, some vocal coaches may have little formal training, and so they rely on their extensive experience as a performer.For example, a native German language speaker who moves to the US may begin providing German diction coaching to amateur vocal students, and over several decades, this vocal coach may develop a broad range of on-the-job experience in coaching German-language singing styles such as lieder and Wagnerian opera.
