Choose the correct key: The original theme song is in the key of B-flat major, so you'll need to play your trumpet in this key.
First line: “Good Old Collingwood Forever”
For the first line, you'll need the following notes: F#, G#, A, G, F#, E.
Second line: “Collingwood Forever, You're the pride of all our hearts”
Notes for the second line: F#, G#, A, B, C#, D#, C#, B.
Third line: “We will follow, follow you, Follow you forever, We will fight, fight, fight for you, Win or lose, we're with you all the way”
Notes for the third line (chorus): F#, G#, A, B, C#, D#, C#, B, A, G#, F#, E, D#.
Repeat the chorus one more time.
You can continue with the other verses of the song, following the same key and note sequence.
Remember, these notes are for the trumpet in B-flat major. If you have a trumpet in a different key, you might need to adjust these notes accordingly.
