Songwriting Basics II

In modal styles of music such as groove based music like pop and dance music, you're limited to 3 modes (if you're not using pentatonics in the melody); dorian, aeolian and mixolydian. (This also applies to rock but it also includes other modes such as harmonic minor if you're Ingwie Malmsteen and Phrygian if you're Metallica). Notice I didn't say minor and said aeolian instead.

Minor implies the ability to move from aeolian to harmonic minor to melodic minor when desired. The reason groove based music is limited to three modes and does not use melodic or harmonic minor normally is because aeolian, dorian and mixolydian don't have a leading tone(aka a raised 7th step of the scale which would cause the music to cadence too forcefully. Something which is undesirable in a groove.

So about those modal chord progressions. They either move by step or frequently use the I IV or V chords. Minor chords are usually placed in inversion only if it makes the bass line smoother (moving by step and not jumping around so much). The motion of a 5th or more is considered a leap and is reserved for climactic points in the melody and sometimes in the bass line as well.

Melody, accompaniment and rhythm all handled. I'll let you worry about lyrics, vocal quality and production. Not my forte.

More could be said about different ways to create unique accompaniments and transitions which is where the art of great composers is truly found. My accompaniments are consistently good and unique. My transitions are weak. Maybe someone else could state their opinions about that.
