True enough. Yet you understand the concept of keys, and key signatures that accompany the staff and dots? The dot height is only the raw note name but it is consistent until some Ahole starts with the C flats and A double flats.
Look on the bright side.There are only 12 notes and most bass is scored between the low E and the lower F# on the G string. The key of the tune determines how those notes are scored. No C flats or A double flats!
You are aware that a major scale has its relative minor pairing using identical written scale with a different starting note.
Children initially learn playing very simple tunes and practicing to books of written out scales. My teacher was apt to remind me that pieces are only mixed up scales.
