Explanation

In fact, this tool doesn't work properly musically. That is, in order for a chord group to be transposed, the tone of that chord group must first be determined and transposed accordingly. For example, let's say you chose the tone "A" from the transpose tool, this actually needs to transpose the tone of the chord group to the F#m tone, which is A Major or related minoru. However, when you select the tone "A", this tool will transpose the first chord in the chord group you added to the sound "A" and match the whole group to that tone. This tool was developed to allow you to transpose instantly. The transposing tool on the chord pages of our chart works musically right because we determine the original tone of the song.
