STAGE-3

a.  Does the song work well with Qactus?

We learned that the guitar with Qactus on 2nd fret is a good match to these keys:

・A
・D
・E

These Keys will change to the following [2nd Stage, 2] into this:

・G
・C
・D

This is the image of the keys that are a good match with Qactus referring to [2nd Stage, 2].
We learned that the key you play the guitar in without Qactus is different from the key you play with Qactus.

The matching keys with Qactus are [A], [D] or [E] when the change key function, or the transposing function, on the website with lyrics & chords is not set at [-2].
(Those of you already familiar playing on QactusCore may think to look for [G], [C], or [D] but that is not the case)

Let’s rephrase that.

We need to try to find the key [A], [D], or [E] because many websites with lyrics & chords show all the songs with the original keys.

But when you play the guitar with Qactus, the transposing function should be set at [-2], and you need to play the guitar following the material of QactusCore based on [-2] as well.（known as the shape key）

You won’t be able to play correctly if you try to look for the key [G] or [C]. (Fortunately, [D] will be ok because both modes have it)

Refer to this chart whenever the material on the website Lyrics & Chords is set at [-2].

Let’s discuss how you resolve keys that doesn’t match well with Qactus.
(This explanation will be a bit longer because it’s important.)

You have many ways to deal with any key.

You can transpose any key into convenient keys with transposition in music theory.

There will be situations that you may need to transpose.

• When you sing a song but it’s hard because the key is not a good match with your voice pitch.
• When it needs to be transposed into the key that is a good match with the musical instrument you have.

It’s ok to transpose is for these two reasons (at least when we play popular music).

In the former case, we won’t be able to play the guitar along with the original version.
However, it will be ok if you play the guitar alone with no accompaniment. This will be a good choice for people who want to play the guitar alone without a band.

Just transpose into convenient keys if you aren’t practicing with the original music track.

Any kind of key can be changed into a particular key that match well with Qactus.
The answer to the first question of the Four Filters is now a “yes.”

Let’s settle down for a moment to avoid things being too complicated.

We are going to try transposition between the same keys because there are many beginners who want to practice along with the original music tracks.

Next part is only for experts who understand music theory. Skip to「b」if you are not at the level of expertise yet.
