Answer: True
In musical set theory, Allen Forte specifically classifies diatonic scales under the set form 7–35.
The harmonic minor and melodic minor scales are considered diatonic because they are seven-note scales.
Answer: False
Harmonic minor and melodic minor scales are not considered diatonic because they do not meet the specific intervallic conditions, such as the maximal separation of semitones, that define a diatonic scale.

The scales corresponding to the medieval church modes were diatonic.
Answer: True
The scales associated with the medieval church modes were indeed diatonic, with different modes arising from starting on various degrees of the diatonic scale.
The Locrian mode was widely used in medieval music theory due to its stable fifth above its reference note.
Answer: False
The Locrian mode was generally avoided in medieval music theory because it lacks a pure fifth above its reference note, resulting in a dissonant diminished fifth.

Answer: True
The establishment of the musical key concept during the Baroque period enabled further transpositions of the diatonic scale, broadening musical possibilities.
Major and minor scales became dominant in Western music primarily because they allowed for more complex dissonances.
Answer: False
Major and minor scales became dominant because their intervallic patterns effectively reinforce a central triad, a core harmonic structure in tonal music, rather than primarily enabling more complex dissonances.
Church modes completely disappeared from Western music after the Baroque period.
Answer: False
While major and minor scales became dominant, church modes continued to appear in various musical contexts, including classical, 20th-century music, and jazz, beyond the Baroque period.

Answer: Cuneiform inscriptions containing musical compositions and a tuning system.
Ancient cuneiform inscriptions from the Sumerians and Babylonians provide evidence of musical compositions and tuning systems that suggest the use of diatonic scales.
Why was the Locrian mode generally not used in medieval music theory?
Answer: It lacked a pure fifth above its reference note, making it dissonant.
The Locrian mode was largely unused in medieval music theory because it lacked a pure fifth above its tonic, resulting in a dissonant diminished fifth that was considered unstable.

Why did major and minor scales become dominant in Western music until the 20th century?
Answer: Their specific intervallic patterns are well-suited to reinforcing a central triad.
Major and minor scales gained dominance in Western music primarily because their intervallic structures effectively reinforce a central triad, a cornerstone of tonal harmony.
In what musical contexts have church modes continued to appear beyond the Baroque period?
Answer: In classical, 20th-century music, and jazz.
Beyond the Baroque era, church modes have maintained their presence in various musical genres, including classical compositions, 20th-century music, and jazz.
How did the medieval conception of tetrachordal structure differ from the modern view?
Answer: It viewed other diatonic scales as differently overlapping disjunct and conjunct tetrachords, based on the D scale.
The medieval understanding of tetrachordal structure, centered on the D scale, involved viewing other diatonic scales as combinations of overlapping disjunct and conjunct tetrachords, differing from the modern two-tetrachord separation.

The 7th degree of a major scale is traditionally called the Leading tone.
Answer: True
In a tonal context, the 7th degree of a major scale is traditionally named the Leading tone due to its strong tendency to resolve to the tonic.
A natural minor scale uses the exact same sequence of notes as its relative major scale but begins on the fifth degree.
Answer: False
A natural minor scale, or relative minor, uses the same notes as its relative major scale but begins on the sixth degree of that major scale, not the fifth.
The 7th degree of the natural minor scale is called the subtonic because it is a whole step below the tonic.
Answer: True
The 7th degree of the natural minor scale is designated the subtonic because it lies a whole step below the tonic, distinguishing it from the leading tone of the major scale.
The seven different diatonic scales, or modes, are generated from any major scale by taking a different degree of that major scale as the new tonic.
Answer: True
The seven diatonic modes are systematically generated by using each successive degree of a major scale as the new tonic, thereby creating distinct intervallic patterns.
Transposition changes the mode of a diatonic scale to a different one.
Answer: False
Transposition does not alter the mode of a diatonic scale; rather, it shifts the entire scale to a different pitch level while maintaining its inherent modal quality.

How is a natural minor scale derived from a major scale?
Answer: It uses the same notes but begins on the 6th degree of the major scale.
A natural minor scale is derived from its relative major by starting on the sixth degree of the major scale and using the same sequence of notes.
What is the interval sequence of the natural minor scale?
Answer: T–S–T–T–S–T–T
The interval sequence for the natural minor scale is T–S–T–T–S–T–T, where T represents a whole tone and S represents a semitone.
Why is the seventh degree of the natural minor scale called the subtonic?
Answer: It is a whole step below the tonic.
The seventh degree of the natural minor scale is termed the subtonic because it is positioned a whole step below the tonic, unlike the leading tone which is a half step below.
How are the seven different diatonic scales, or modes, generated from a major scale?
Answer: By starting on a different degree of that major scale as the new tonic.
The seven diatonic modes are generated by using each successive degree of a major scale as the new tonic, preserving the intervallic relationships but shifting the tonal center.
Which of the following is NOT one of the seven modern modes that constitute the collection of diatonic scales?
Answer: Harmonic Minor
Harmonic Minor is not considered one of the seven modern diatonic modes; it is an alternative seven-note scale with a different intervallic structure.
What effect does transposition have on the mode of a diatonic scale?
Answer: It preserves the mode of the diatonic scale.
Transposition shifts a diatonic scale to a new pitch level but fundamentally preserves its modal identity.
