In this masterclass, Professor Holl gives general indications related to the main aspects of voice training: pronunciation and projection when performing a phrase. He also advises the student on the need to create her own personality as a singer. The singer has to avoid voice gaps or leaps and rather imagine and create a voice line. General musical aspects such as dynamics, articulation and expression are also present.
As a pianist, Holl gives corrections to the piano part in concepts like character, sound, articulation and dynamics, and makes a comparison with Schubert's music.
