What was etruscan painting mostly used for?

The Etruscan art was commonly used as a decoration of tombs.  Mostly of the Etruscan arts were unearthed from tombs mostly around temples with terracotta fragments of architectural sculptures.  It was also used in pottery and in vase painting mostly depicting everyday life.

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.
