The two kinds of key signatures are major and minor.
a scale that is diatonic and pentatonic
Minor and major are two diatonic scales. A minor has no key signature. The key signature of A Major is three sharps, F# C# G#.
F major, B-flat major.
In the order of flats in key signatures, even if the melody skips the B-flat, the key would contain it, because there is no such key with only an E-flat.
Both scales use eight diatonic notes, they both sound consonant and they use the same key signatures.
the answer is mediant
Maybe wrong but pretty sure its a key of A diatonic
The keys of Eb Major and c minor have three flats in their key signatures: Bb, Eb, and Ab.
It depends what key is this tonic triad in.
There are several key signatures that contain sharps.
nobody answer
Diatonic decoration only uses notes that are in the key signature(white keys on piano for C major). Chromatic decoration uses all notes including those outside the key signature (white and black keys for C major).
