What's the Key of this Piece? - Music Theory

The video tutorial explores how to identify keys in melodies without key signatures by analyzing accidentals. It begins with an introduction to accidentals and their role in determining minor keys. The tutorial then focuses on a melody in G minor, explaining how accidentals like F# and F natural indicate a minor key. It discusses modulation, showing how the melody transitions to C minor, and concludes with practice on spotting key changes.

What is the significance of having both sharps and flats in a melody without a key signature?

• It shows the melody is in a pentatonic scale.

• It means the melody is atonal.

• It suggests the melody is in a minor key.

• It indicates a major key.

In a harmonic minor scale, which note is typically raised?

• The sixth note

• The seventh note

• The fifth note

• The third note

What key signature is associated with G minor?

• Two flats

• One sharp

• No flats or sharps

• Three sharps

Why might a melody start on a B flat but not be in B flat major?

• Because it is in a different time signature

• Because it is in a different mode

• Due to the presence of an F#

• Because it uses a pentatonic scale

What does the presence of B natural in a melody suggest about the key?

• The melody is in G major.

• The melody has modulated to another key.

• The melody is in C major.

• The melody is in F minor.

What is the significance of having an E flat but not a B flat in a melody?

• It indicates a modulation to a major key.

• It suggests a modulation to another minor key.

• It shows the melody is in a whole tone scale.

• It means the melody is in a diminished scale.

What key does the melody modulate to by the end?

• F minor

• A minor

• D minor

• C minor

Why is a B natural followed by an A flat avoided in melodic writing?

• It leads to a tritone interval.

• It forms a perfect fourth interval.

• It results in an augmented second interval.

• It creates a diminished interval.

What is the role of the raised 6th and 7th degrees in a melodic minor scale?

• To create a major scale

• To avoid augmented intervals

• To simplify the melody

• To enhance the harmonic minor scale

How does the melody confirm its modulation to C minor?

• By starting on a G note

• By ending on a C note

• By using a D flat

• By avoiding any sharps
