Ternary & Rondo Flashcards
What is the structure of a ternary form?
It consists of three sections: A, B, and A.
What are the characteristics of the A sections in ternary form?
Both A sections usually consist of multiple phrases, start and end in the tonic key, and conclude with a perfect authentic cadence (PAC).
What is a perfect authentic cadence (PAC)?
A perfect authentic cadence is a musical resolution that typically involves the progression from the dominant (V) to the tonic (I) chord.
In ternary form, how does the B section differ from the A sections?
The B section is often in a different key or in the parallel major or minor, usually starts and ends in the same key, and may conclude with a PAC or half cadence (HC).
True or False: The first A section in ternary form must always start and end in the tonic key.
False. The first A section may modulate to another key.
Fill in the blank: The B section in ternary form usually ends with a _______.
PAC or HC.
What is a bridge in the context of ternary form?
A short passage that leads from the end of the B section to the second A section.
What is the role of the tonic key in the A sections of ternary form?
Both A sections typically start and end in the tonic key.
What type of cadences can the B section conclude with?
The B section may conclude with either a perfect authentic cadence (PAC) or a half cadence (HC).
List the key characteristics of the B section in ternary form.
- Often in a new key or parallel major/minor
- Usually starts and ends in the same key
- Ends with PAC or HC
- May be preceded by a bridge.
What distinguishes ternary form from rounded binary form?
Certain features such as self-contained sections and separation by a strong cadence
In ternary form, the A and B sections are more independent than in rounded binary.
In ternary form, how does the length of the second A section compare to the first A section?
The second A section is likely to be either the same length as or longer than the first A section
This contrasts with rounded binary, where the second A is generally the same length or abbreviated.
What is a common feature of the two parts in rounded binary form?
The two parts are almost always grouped together by repeat signs, ||: A :: B A :
This indicates a strong connection between the A and B sections in rounded binary.
Are repeats common in ternary form?
There may be repeats within the A or B section, but the B and second A section are generally not repeated together as a unit
This highlights a key difference from rounded binary form.
What is the structure of ternary form?
ABA or ABA’
Ternary form consists of three sections: A, B, and A (or A’).
Are repeats allowed within sections A or B in ternary form?
Yes, repeats are allowed within A or B, but not together.
This means that while the A section can repeat certain phrases, it will not repeat the entire A section in conjunction with B.
What is the typical key relationship in the A and B sections of ternary form?
The A section typically starts and ends in the same key, as does the B section.
This key relationship is essential for maintaining the structure and coherence of the form.
What does PAC stand for in the context of ternary form?
PAC stands for Perfect Authentic Cadence.
A PAC is a strong resolution that provides a sense of closure to a musical phrase.
How does the B section of ternary form compare to the A sections?
The B section is usually substantial and may end with a PAC.
This indicates that the B section often has more musical material or complexity compared to the A sections.
How does the length of the second A section compare to the first in ternary form?
The second A section is often the same length as or even longer than the first A section.
This can create a sense of development or variation in the music.
