Ok, assuming you are referring to a Bb Trumpet:
The B MAJOR scale is as follows:
B - C♯ - D♯ - E - F♯ - G♯ - A♯ - B
To get that to a minor scale, you lower the 3rd, 6th, and 7th scale degrees:
B - C♯ - D - E - F♯ - G - A - B
Because you mentioned the trumpet transposition I'll put that in here too.
Because you have a Bb trumpet, you need to transpose. The easiest way to transpose is to use a "circle of fifths" or "circle of fourths" its the same thing. It just depends on which way you go around.
So using the circle of fifths you would need to play the Db/C♯ Scale. (they are enharmonic and are the same)
Which is:
Db - Eb - F - Gb - Ab - Bb - C - Db
Minor:
Db - Eb - Fb (E) - Gb - Ab - B - Cb (B) - Db
The reason why I'm writing Fb instead of E is because of the theory of writing scales in that there can only be one of each note in a scale (excluding the root)
Just for kicks, heres the C♯ scale
C♯ - D♯ - E# - F# - G♯ - A♯ - B# - C♯
Minor:
C♯ - D♯ - E - F♯ - G♯ - A - B - C♯
Concert C is the clarinet's written D, so the notes for the major scale are D E F# G A B C# D
On trumpet, concert G is written A.
It depends on which instrument.
A, b, c, d, e, f, g, a. (Natural minor)
The notes for E minor pentatonic are E, G, A, B, and D. All naturals!
There is no relationship between eighth notes and a concert scale.
The A Flat Natural Minor Scale
F relative Minor Scale has the following notes:BbEbAbDb
7
The C major scale and its relative minor, the A minor scale. C Major.
Concert C is the clarinet's written D, so the notes for the major scale are D E F# G A B C# D
On trumpet, concert G is written A.
A diatonic scale is simply a regular major or minor scale.
A minor scale typically consists of seven steps or notes.
The harmonic minor scale, in relation to the natural minor scale, has a raised 7th scale degree. This happens with the use of accidentals rather than the key signature.
It depends on which instrument.
It is a scale with only five notes as opposed to the usual 7 notes in a major or minor scale.
