Add First Species (1:1) counterpoint to the provided cantus firmus, being sure to use consonances exclusively while avoiding parallel/direct fifths/octaves. Label each harmonic interval number between the staves, using a simple interval number even if the true interval is a compound interval (e.g. write "3" instead of "10" even if the interval is truly a tenth). The first interval number label has been done for you. You may repeat (only!) one note in your added melody, but you are not required to. Remember that contrary motion is always good!
