“He who cannot sing / cannot play either” This statement by Johann Mattheson is drastic but not entirely new. Throughout many centuries of musical history, prestigious and well-regarded musicians, composers and theorists have discussed and reinforced this topic – the relationship between the human voice and any musical instrument, between singing and playing. Why should one match the human voice in playing? For the sole purpose of being historically correct? After all, it is generally believed that music is the language that everyone understands…In it listening and understanding are, ideally, closely linked.
