TRANSCRIPT:
Greetings everyone! We covered a lot of basic stuff in the last video on piano-keyboard harmony, but the understanding we gained of those terms and how they apply will help us communicate. So if you haven’t yet waded through that first video and spent the entire week completing the 20 repetitions of the practice instructions, you should stop right now, go back and do so. The link is in the Description.

Only the practical application of theory is of value to you. Right?

That said, we continue. Here is a question that we will answer later in this video: Why does the key of G Major have a sharp in its key signature? Watch for the answer!

THE PRACTICE – Repeat the following 20 Times in one week (or approximately Three Times Daily for Seven Days).

We learned last time how the C Major scale is constructed of two tetrachords – four notes – each having the same configuration: whole-tone, whole-tone, semitone. [play and say, C D E F, G A B C, also do re mi fa, sol la ti do’.]

The first tone of the second tetrachord, G, or SOL [play], is a perfect fifth above C, the DO [play 12345 5]. That is the direction we want to go – we want to transpose or move the entire major scale up a fifth.

So we make the 2nd tetrachord of C major the 1st tetrachord of G Major, the new DO. [play the new do re mi fa]

Now we only have to find the 2nd tetrachord of the new key of G Major; with what note does this new upper tetrachord begin? We know both tetrachords have that same configuration, W W S, and are a whole-tone apart. The first tetrachord is G A B C. Play those keys starting with the 4th finger of your LH. [G A B C / DO RE MI FA]

Now, the 2nd tetrachord of G Major must start a whole-tone above that last note C, which is D. Play D with your RH thumb. [D / SOL]

Now we apply the configuration, W W S, to the new second tetrachord. What note is a W above D / SOL? E / LA.

W above E? F#! Remember, a W has one key in the middle, between the two keys of the interval.

Finally, the Semitone. What note is a S above F-sharp? G. Thus, we have built our new, second tetrachord, for G Major. Incidentally, this F-sharp – TI – is also the Leading Tone of the key of G.

Now, play the G major scale, starting with finger 4 of the LH, on G. Name the notes of the two tetrachords: G A B C | D E F# G’. Also in solfège: d r m f | s l t d’. You should also play the two tetrachords in reverse, descending. [G F# E D | C B A G; d’ t l s | f m r d]

Congratulations! You have succeeded in transposing the C Major scale up a fifth, to G Major. Now, about the theory.

The THEORY
Notice, there is now one sharp in the key signature, for the key of G Major. “Theory” is descriptive, so can you describe or explain why that sharp is there? We add the F sharp to the key signature of G Major, so the upper tetrachord of the scale will have the same configuration of intervals as the lower tetrachord: Whole-tone, Whole-tone, Semitone. Otherwise, the transposition is faulty, leaving this scale with no Leading Tone. In a Major Scale, both tetrachords are the same: W W S. Hence, we write a sharp sign at the beginning of the staff, on the F line.

You may have noticed that today, we did not play G Major scale with the “standard fingering.” That is because we are now approaching the keyboard from the standpoint of transposition and harmony study, NOT performance. That said, …

You should also practice scales with standard fingerings, and there are videos on the channel to show you how to do that. The G Major Scale practice video is linked below, so, be sure to watch that one, as well as the other playlists.

As for today’s video, Do the 20-times-per-week or 3-times-daily practice procedure for one week, whichever works for you, and Have a good one! Thank you for watching.
