Mode Tweaks ("Sakura" Case)

[pikurasa]

For this code:

I expect the result to be the same as Aeolian in A.

However, MB is currently not able to find some of the pitches. I think it is because it is expecting that the user start with a pitch other than "La" **.

Here is a picture from a Japanese children's music book (page 1). It has "La, La, Ti" for the first three notes.

** Currently, "Fa, Fa, Sol" for "E In" and "Movable Do" results in the intended melody for "Sakura". I suppose this is to indicate that we are starting from the 4th scale degree (Do, Re, Mi, Fa)?

Here are all my testing files: Sakura-Testing-Files.zip. This is part of my research for #2020

[pikurasa]

I tested Sakura as "Scale Degree" in "E In" and I found that I must specify the scale degrees 3, 3, and 4.

I am expecting 4, 4, and 5, especially in light of the behavior for "Movable Do" as mentioned in:

I suppose this is to indicate that we are starting from the 4th scale degree (Do, Re, Mi, Fa)?

I suppose this is because "Sol" is skipped -- is that correct?

Most musicians would count "Sol" as a scale degree, even if it is being skipped for a pentatonic scale. For example, this reference has "Sakura" beginning on 4th scale degree. (It also has the scale that Wikipedia calls "In" as "Hirajoshi", which is confusing. Please correct me if I am mistaken.)

[pikurasa]

Theoretically, if we rewrite Sakura for Scale Degree, then we should get the expected results. I will do this soon-ish.

I did it.

It gets the correct pitches, but the octaves are displaced (known issue).

Lilypond Output:
Sakura-SD.zip

There are a couple strange things about the Lilypond Output:

• Octaves seem displaced differently than the sounding pitches when running in MB
• I don't understand the key calculation. It is giving sharps that are not ever needed. There is no pitch for G or D, so why sharp them? The fallbacks for E In should be E Phrygian.

I hope this is helpful. Once we fix the octave issue, I will send a PR for it to be in the examples folder. It is a good example for how scale degree block works.
