Dave Gore coined the phrase physics of music. I have applied this to some riffs or ear worms.
Shaking all over. This riff is a guitar boogie. Which goes the E- E plus 1 octave- D and then B four notes.
The interval between the 2 E is an octave This sounds good then one note lower the D Then B which is a perfect fifth to the low E and an descending perfect forth from The high E. D is also a minor 7th from low. E being the tonal centre of the riff.
The physics of the intervals makes it catchy. The intervals all sound good.
This riff is C D D# C and then G G# G G#
However most play E F# G E A A# A A#.
C to D is 2 semitones then D# this gives tension something must resolve the tension it goes back to C. Every body happy. Then a G which is a perfect fith from C. Then add tension with G# and resolve with a G Then back to C which is a descending perfect 4th.
Again the physics make it catchy.
# means plus 1 semitone or sharp b means minus 1 semitone or flat note lower case b. C# and Db are the same note.
