There are other approach to changing keys as well.
1) Finding a common tone in the two keys
So I am going to write out the scales in two different ways:
C D E F G A B C (C Major)
C D Eb F G Ab Bb C (Eb Major)
Eb F G Ab Bb C D Eb (Eb Major)
E F G A B C D E (C Major)
If you can see, the scales are pretty parallel to each other. Now if you do any type of run (especially a scale), you can quickly lead into the next key. You do have to experiment for yourself but it has so many different ways to change the key that its pretty efficient.
2) Finding a common chord in the two keys
This is what I like to call the "pivot" key change. As you play through, you will find a chord that lies in both keys.
C Dm E m F G(7) A m B dim
Cm Ddim Eb Fm Gm Ab Bb(7)
This key transition is not as smooth for this scenario. However it is still possible. If you break down the chord and make a melody, then the transition is alot more defined and helps transition easily. I will do an example with every chord.
C - F - Ab - Ab/Bb - Eb
Dm - F/A -Bb - Bb7 - Eb
Em - G7 - C - Bb7
F - Dm (D7 for the alternate dominant chord) - Gm - Ab/Bb
G7 - C - F - Ab/Bb - Eb
Am - G - F
B flat is the enharmonic spelling of C natural. Basically, it's the same note; there would be no modulation.
You would play a F7 chord to change from the key of C to the key of B flat.
B-flat
If you are talking about key signatures Bb major has 2bs but Bb minor has 5bs.
A flat key is a key that has a flat on its tonic note. A sharp key is a key that has a sharp on its tonic note.
Bb is the 3rd black key out of the grouping of 3. this is the same for every octave of Bb.
Piano plays in c.. To transpose to Eb lower the written note one line or space and use the key signature of b and e flat and add the written key signature
The key of B flat on the piano has two flats (Bb and Eb).
The key signature with only a B-flat is either F major or D minor.
B-flat
If you are talking about key signatures Bb major has 2bs but Bb minor has 5bs.
A flat key is a key that has a flat on its tonic note. A sharp key is a key that has a sharp on its tonic note.
Bb is the 3rd black key out of the grouping of 3. this is the same for every octave of Bb.
F# minor, which has 3 sharps in the key signature.
Piano plays in c.. To transpose to Eb lower the written note one line or space and use the key signature of b and e flat and add the written key signature
it means B flat on the piano
Yes, it is. The "A" on a flute is the same as the "A" on a piano, unlike the (common, soprano) clarinet which in the key of "B flat".
A flat lowers the note by a semitone. As a key signature, a single flat indicates the key of F, meaning your B should be flat. Two flats are E and B, meaning the key is therefore B flat. B, E and A flat indicate the key of E flat ... and so on.
Starting with B flat, the third black key in the group of three, the next note would be D flat, the next black key. E flat would be the next note also the next black key. E natural is the white key one to the right then the next white key which would be F natural. The final note is A flat which is in the middle of the three black keys.
