Over our C minor chord, we get a triplet figure of all B♭s, making the chord a C minor 7. This is followed by the use of a passing tone (Ab) to get from the 7th to the 5th. Finally, over the B♭, we have an F (the fifth of the chord), moving to a G (the 13th, another tension).
Consider what one person can accomplish musically on a MacBook alone. With a DAW (digital audio workstation) like Ableton Live or Logic Pro, a few royalty-free sample packs, some cheap-to-free VSTs/plugins, and a bit of a musical ear, the “bedroom producer” now has all the ingredients she needs to create commercially viable music.
