As the tutor for my school's music department, I spend a lot of time helping students drill intervals. However, I only have a handful of songs to recommend recognition.
P8 — Somewhere Over the Rainbow
P5 — Also Sprach Zarathustra
P4 — Here Comes the Bride
m7 — Somewhere (West Side Story)
And there's the extent of my help. Everything else I work as either arpeggios or scales. What are good pieces to help my students? Particularly Tritone and the Major and Minor 6ths.
