A choir rehearsing in G major uses movable-do solfège. The conductor asks the sopranos to sing 'do.' What pitch should they sing?
AC, because do always means C in solfège
BG, because do represents the tonic of the current key in movable-do
CD, because G is the dominant and the tonic must be a fifth below
DThe answer depends on whether the piece uses a major or minor scale
In movable-do solfège, 'do' always represents the tonic — the root — of the current key, not an absolute pitch. In G major, G is the tonic, so G is 'do.' This is the defining feature of movable-do and its primary source of confusion: students trained with fixed-do (where do = C always) must retrain their association. The movable-do system's power is precisely this flexibility: by making 'do' mean 'home,' the same syllable sequence encodes the same functional relationships in every key.
Question 2 Multiple Choice
A student wants to develop absolute pitch recognition and connect solfège directly to staff notation. Which system would be more useful for that goal?
AMovable-do, because it creates stronger pitch memory through functional associations
BFixed-do, because each syllable corresponds to a specific pitch class regardless of key
CEither system works equally well for developing absolute pitch
DNeither system — solfège is incompatible with absolute pitch training
Fixed-do assigns permanent pitch identities to syllables: do = C, re = D, mi = E, etc. This creates direct associations between syllable sound and absolute pitch, supporting absolute pitch recognition and connecting naturally to staff notation. Movable-do is better for functional hearing and sight-singing across keys, but shifts the syllable-pitch mapping with each key change, making it less useful for absolute pitch training. The two systems have genuinely different pedagogical strengths, which is why the choice between them is a real debate in music education.
Question 3 True / False
In movable-do solfège, the syllable 'ti' represents a different scale-degree function depending on which key you are in.
TTrue
FFalse
Answer: False
In movable-do, 'ti' always represents scale degree 7 — the leading tone — regardless of key. In C major, ti = B; in G major, ti = F#; in F major, ti = E. The absolute pitch changes, but the functional identity is constant: ti is always the note a half step below do, with the characteristic tension that pulls toward do (the tonic). This is exactly movable-do's advantage: the syllable encodes the function, so ti-do always means the same resolution regardless of key.
Question 4 True / False
Fixed-do is more widely used in the United States for choral sight-singing because it connects more directly to notated music.
TTrue
FFalse
Answer: False
Movable-do is the dominant system in Anglo-American choral pedagogy, including most U.S. school and choral settings (e.g., the Kodály method). Fixed-do is more common in France, Italy, and conservatories following European traditions. The statement gets the geographic distribution backwards. Movable-do is preferred in American sight-singing pedagogy because it emphasizes functional relationships that transfer across keys, making it more practical for the variety of keys encountered in choral repertoire.
Question 5 Short Answer
What is the practical advantage of movable-do over fixed-do for a sight-singer encountering an unfamiliar piece in an unfamiliar key?
Think about your answer, then reveal below.
Model answer: In movable-do, you only need to identify the tonic of the key, then assign 'do' to it. Every other scale degree gets its syllable based on its position relative to the tonic — the same syllable sequence (do re mi fa sol la ti do) works in any key. You can then sight-sing the melody by translating scale positions to syllable shapes without knowing what the absolute pitches are named. In fixed-do, you would need to translate each note to its absolute pitch class before singing, a process that does not generalize as easily across keys.
Movable-do's power is its key-independence. A melody that ascends do-re-mi-fa-sol in C major uses the exact same syllables in F-sharp major, even though the absolute pitches are completely different. This is why movable-do is better for sight-singing and melodic ear training: the syllables encode functional patterns — steps, leaps, characteristic intervals — that the singer recognizes and reproduces in any tonal context without needing to re-learn the syllable mapping for each new key.
