A movable due refers to what is it each note receiving a demarking they do marking being used multiple times in a scale they do marking being assigned to the first note of a scale no matter which pitch it starts on, or the demarking being fixed on middle C, and all other notes are based off of it

A movable due refers to the way in which solfege syllables are assigned to the notes of a scale based on the tonic or starting pitch of the scale. In movable do, the syllables "do," "re," "mi," etc. are assigned to the notes of the scale, regardless of their actual pitches. The tonic or starting pitch determines which note is assigned the syllable "do." This means that the solfege syllables can be used for any scale, in any key, by simply assigning "do" to the tonic note and applying the appropriate syllables accordingly. Movable do allows for a flexible and adaptable system of solfege that can be used in different musical contexts.

A movable due (also known as movable tonic or movable solfege) refers to a system used in music theory to understand and notate pitches in a scale.

In this system, each note is given a solfege syllable (such as do, re, mi, etc.) to represent its position in the scale. The marking for each note is based on the tonic, which is the first note of the scale. The tonic can be any pitch; it is not fixed to a specific note on the musical staff.

The movable due system allows musicians to use the same solfege syllables for different scales. For example, if you start a scale on C, the pitches will be labeled as follows: C is do, D is re, E is mi, and so on. However, if you start a scale on G, the same solfege labeling would be applied: G is do, A is re, B is mi, and so on. The solfege syllables are movable and adjust to fit the starting note of the scale.

This system is beneficial because it creates a consistent framework for understanding and analyzing music across different scales and keys. It allows musicians to easily identify and communicate the relative pitches within a scale regardless of the starting note.

To determine the movable due markings for a specific scale, you need to identify the tonic (first note) of the scale. Once you know the tonic, you can apply the solfege syllables in a movable pattern to label each subsequent note in the scale.

A moveable "do" refers to the marking system used in functional solfege, where each note is assigned a syllable based on its function within a scale. In this system, the syllable "do" is used to represent the tonic or first note of a scale, regardless of the pitch it starts on. The other notes in the scale are then assigned different syllables relative to the tonic. This allows for easier transposition and recognition of musical patterns across different keys.

For example, in C major, the scale would be: C (do) - D (re) - E (mi) - F ( (sol) - A (la) - B (ti) - C (do).

If the same melody were transposed to another key, such as G major, the syllables assigned to each note would remain the same while the pitches change: G (do) - A (re) - B (mi) - C (fa) - D (sol) - E (la) - F# (ti) - G (do).

This moveable "do" system is widely used in music education to facilitate learning and understanding of musical relationships.
