Thanks to Sofia2015 for suggesting this one! The Aristocats is one of my favorite Disney movies, even if it's not mine.
Setting: Before the events of "The Day the Music Died". James, Amber, and Queen Melinda are around the piano.
Amber: Any time you're ready, James. (cries out as James slides his hand across the keys and bumps into her) Ouch! Mother! He did it again!
James (under his breath as he sits at the keyboard): Snitch!
Queen Melinda. Oh, James. Now, both of you settle down, and play me your pretty little song, please?
Amber: All right.
(sings) Do mi so do do so mi do
Every truly cultured music student knows
You must learn your scales and your arpeggios
Bring the music ringing from your chest
And not your nose
While you sing your scales and your arpeggios
James: If your faithful to your daily practicing
You will find you progress is encouraging
Do mi so mi do mi so mi fa la so it goes
When you do your scales and your arpeggios
Amber: Do mi so do-
(Fast piano music playing)
James, Amber, Queen Melinda: Do mi so do do so mi do
Do mi so do do so mi do
Though it seems at first it doesn't show
Like a tree ability will bloom and grow
(King Roland comes in and joins them)
If you're smart you'll learn by heart what every artist knows
Your must sing your scales
And your arpeeee-ee-eeggioooooooooos!
