It depends on which key you are referring to, all the keys with flats are:
F major (1 flat)
B-flat major (2 flats)
E-flat major (3 flats)
A-flat major (4 flats)
D-flat major (5 flats)
G-flat major (6 flats)
C-flat major (7 flats)
Likewise the relative minors are:
D minor (1 flat)
G minor (2 flats)
C minor (3 flats)
F minor (4 flats)
B-flat minor (5 flats)
E-flat minor (6 flats)
A-flat minor (7 flats)
The key of C Major consists of these notes: C, D, E, F, G, A and B.The key of C Harmonic Minor consists of these notes: C, D, E-flat, F, G, A-flat and B.The key of C Melodic Minor consists of these notes: C, B-flat, A-flat, G, F, E-flat and D. However, when played ascending as a scale, the sixth (A-flat) and seventh (B-flat) notes/degrees would be sharped, leaving us with B and A. On the way back down they are restored to A-flat and B-flat.
C flat Major
B flat, E flat, A flat, D flat, G flat, C flat, F flat. It's the opposite order to that of the sharps in a key signature.
G flat, A flat, B flat flat, C flat, D flat, E flat, F natural and G flat.
The key of B flat major, or g G minor, has two flats. The flats are B flat and E flat.
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.
The dominant is the 5th, which in the key of A-flat major is E-flat. Then an E-flat major triad contains the notes E-flat, G, and B-flat.
It shows which notes are flat or sharp. To read the key, a clef is also required, as that indicates the positioning of notes within a staff.
The key of C Major consists of these notes: C, D, E, F, G, A and B.The key of C Harmonic Minor consists of these notes: C, D, E-flat, F, G, A-flat and B.The key of C Melodic Minor consists of these notes: C, B-flat, A-flat, G, F, E-flat and D. However, when played ascending as a scale, the sixth (A-flat) and seventh (B-flat) notes/degrees would be sharped, leaving us with B and A. On the way back down they are restored to A-flat and B-flat.
The key signature indicates which notes are sharp, natural, or flat. Every key has a specific signature.
No. An A flat is the same as a G sharp and an A sharp is the same as a B flat. A flat and A sharps are two different notes, although they are the same distance from A.
B flat
There is not three notes in any scale or key, if you are asking about the accidentals, there is one flat (Bb) in the key signature plus an additional C sharp for the harmonic minor scale.
The F major scale consists of the following notes: F - G - A - B Flat - C - D - E - F
A key signature is basically a collection (or bunch) or sharp or flat symbols at the start of a line of music which tells you which notes are going to be regularly played sharp or flat.
The IV chord in the key of B flat would be E flat so the triad notes would be e flat, g, and b flat (on keyboard) for guitar it would be e flat, b flat, e flat, g, b flat, and e flat. Played at the 11th fret as a bar chord in standard tuning.
There eight notes in an octave, and it depends on what key you are in as to what exact notes you have, like in the key of D flat you have: d flat, e flat, f, g flat, a flat, b flat, c, then back to d flat.
