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 minor key with three sharps is B minor. In the key signature of B minor, the sharps are F#, C#, and G#. This key is the relative minor of D major, which also has two sharps in its key signature.
Bb Eb Ab go up the keyboard three notes and it's relative major is Eb...which has three flats..therefore..c minor will also have 3 flats
None. No key signature contains a mix of flats and sharps.
A key signature is the placement of sharps or flats at the beginning of a piece of music which determines what the key of a song is and unlike the time signature it is repeated every line; here is a list of all the possible keys you can write in:C Major/a minor (no sharps and no flats)Sharp Keys:G Major/e minor (1 sharp)D Major/b minor (2 sharps)A Major/f♯minor (3 sharps)E Major/c♯minor (4 sharps)B Major/g♯ minor (5 sharps)F♯ Major/d♯ minor (6 sharps)C♯ Major/a♯ minor (7 sharps)Flat Keys:F Major/d minor (1 flat)Bb Major/g minor (2 flats)Eb Major/c minor (3 flats)Ab Major/f minor (4 flats)Db Major/bb minor (5 flats)Gb Major/eb minor (6 flats)Cb Major/ab minor (7 flats)
E flat major or C minor.
The minor key with three sharps is B minor. In the key signature of B minor, the sharps are F#, C#, and G#. This key is the relative minor of D major, which also has two sharps in its key signature.
F# minor, which has 3 sharps in the key signature.
Bb Eb Ab go up the keyboard three notes and it's relative major is Eb...which has three flats..therefore..c minor will also have 3 flats
F# minor has a key signature of 3 sharps, whereas Gb minor has a key signature with 6 flats. It's easier to use key signatures with fewer flats/sharps.
The key signature for D Minor is 1 flat. Here is the difference between D major and D minor: D Major: D E F# G A B C# D D Minor: D E F G A Bflat C D However, there are 3 commonly used forms of Minor Scales. The above is called the "natural minor", or Aeolian Mode. In the harmonic minor scale, the 7th note is raised one semitone, to C#. However, this added sharp does not appear in the key signature. In the melodic minor scale, the 6th and 7th notes are raised in ascending, to B and C#, but restored to the natural minor form in descending. However, these changes do not appear in the key signature. In the D minor pentatonic scale, used frequently in Rock, only the following notes are used: D - F G A - C D This form can be notated with or without a key signature, but a key signature of one flat (Bb) lets us know that D is the tonic!
B minor. It is called the "relative minor" of D major because in essence they are the same scales however they have different root notes. B minor/D major are the "same" as C# locrian, or E dorian, or F# Phrygian etc.
The key signature with 3 sharps is A major.
That's a key that only exists in theory and not in practice (called an imaginary key), because it would have more than 7 flats. The key of G minor has 2 flats (Bb and Eb), so then key of G-flat minor would then have 9 flats. (The notes of that imaginary scale would be: Gb, Ab, Bbb, Cb, Db, Ebb, Fb, Gb) The enharmonic equivalent to G-flat is F-sharp, and F-sharp minor has 3 sharps.
Flatten the third and seventh notes in the scale. Therefore, if you're in the key of A major the notes are A, B, C#, D, E, F#, G#, A. Therefore, flattening the 3 and 7, you end up with A, B, C, D, E, F, G, A. By the way, Am is the relative minor of the key of Cmajor, which has no sharps or flats.
3/4 is a time signature, not a key signature.
Each key signature represents two possible keys. Each of the major keys has a relative minor key and vice versa. A key signature with one (F) sharp could either be G major or E minor. If the minor and major scales bear the same key signature, they are called related scales. In this case, G major is the relative of E minor. Here is what you should look for to determine if a piece is in minor: Starting and Ending pitches/chords- pieces and minor usually but not always start and end on do and the tonic (I) chord of the scale Raised seventh scale degree (ti instead of te)- In the harmonic and melodic minor scales the seventh scale degree is raised a half a step (but in melodic minor it has a raised sixth as well on the way ascending, but follows pure minor, descending. To tell if a note is part of the ascending or descending scale look at the following note: if it is higher the note is part of the ascending scale- if it is lower, the note is part of the descending scale.) The raised seventh or sixth never appears on the key signature. Also, bear in mind that the related scales in question are only three notes apart. For example, you know the key signature of G major, but not that of E minor. So you count three notes down, thus, G, F, then E, now you know two things about E minor. One, its key signature id F sharp, and two, it is a relative of G major. To get to the major scale, always count upwards. To get to the minor scale, count downwards. I reckon that might have been a little confusing.
Bb, Eb and Ab. In the key of Eb major OR C# minor.
