DarqueCadenza, scales are the notes played in order, like do re mi fa so la ti do. When there are no sharps or flats it is the key of C. Usually on violin the first scale and fingering pattern is in the key of D, which is two sharps. This teaches a basic hand position for the left hand finger patterns and you practice them to learn to play in tune by placing the fingers precisely in the correct places. I’d encourage you to view your fear of tuning the violin like a boogeyman fear. It is unrealistic. I’ve had strings break but never snap back and hit me in the face. I’ve never heard of that happening to anyone.
