13. Gustav creates a melody of four notes with a stepwise motion. What is MOST likely the pattern of these notes? a whole step, two half steps, a whole step
a half step, three whole steps
four half steps
two whole steps, two half steps

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.
