How do I know wether to do up bow or down bow on violin sheet music?

The are marks above every note in the beginning of each measure, there is a different sign above the note that indicates up, and another that indicates down. Either look up or ask your teacher which sign means what. Hope this helps!

Explanation:

including the octave, the answer would 8 notes in a major scale with one note being played twice. ex) c major scale includes: c, d, e, f, g, a, b, c

notice that c is played twice

however, if you were to ask me how many different notes are in a major scale- the answer would be 7.  

the music of the classical period was often written to be more accessible and enjoyable for all people, rather than just the wealthy. how does contemporary music reach all audiences instead of selected patrons? select a contemporary genre of music and discuss how it reaches varied audiences. be sure to identify your musical choice within your discussion.
