Can someone please help with this? Half steps and whole steps. It’s for band

Bb, C, D, Eb, F, G, A, Bb
Explanation: The sequence for a major scale is always as follows:
Starting note,
Whole step up,
Whole step up,
Half step up,
Whole step up,
Whole step up,
Whole step up,
And a Half step up, which puts you back on whatever you started on.
When determining scales and key signatures like this, think of a piano. There are two sections that repeat across the whole thing, a section with three white keys and two black keys, followed by four white keys and three black keys. Think of the first note as C, or the note on the left of the first series of keys, three white, two black. The white keys are C, D, and E. And there are two black keys in between them because they are a whole step apart. Now the second series is F, G, A, and B, and the reason there are black keys in between them is because they too are each a whole step apart. Now notice the lack of a black key in between B and C, and E and F, these notes are a half step apart. And if you mimic this sequence replacing C with your starting note, you will easily be able to determine the Key signature and major scales.

The gregorian chant was a major cultural milestone in the middle ages. it was one of the first codified forms of music meant to be played as written, where previously it was difficult to mass-produce and disseminate any music. what's more, these chants were also some of the first examples of musical notation: the notes and bars of today's music sheets are a reflection of centuries of evolution beginning with these chants. it became official throughout the entirety of the catholic church, meaning that nearly all of europe followed this musical notation and styling.

True, all people no matter what deserve a fair trial.
