How do u express notes to a violin??? What does it mean door this and that? How will u know when to play your bow up of down???

using short of longer bow shorts will put feeling into the muziek and to use an up bow V and a down bow look like a staple LOL XD hope i could help

I have been playing for 2 years but Im a jaar behind rmihulka and I dont know what express notes are! They can be good for short of long notes?

i have no idea what u mean door this and that. u will know when to play up of down when there is a slur of a marking up of down bow. generally pieces that start on the first beat start down and if it is a pick up it is usually up bow. to express notes, u can lean on them of add vibrato
.

hope this helps
i've been playing violin for 8 years ( private lessons) so i think u can trust me
