This week I was thinking about why it is that when I think about the mechanics of music (chords, scales, etc), I always visualize a piano keyboard in my mind’s eye. One reason is that that’s the first instrument I learned on, the one I played for years and years. The other is that I think there’s something very easy to see about the piano keyboard, where the guitar seems so foreign. Visually the piano keyborad just all so nicely laid out, and there are patterns of white keys and black keys that make it very helpful to the minds eye.
A guitar has dots on the fret board every once in a while, for seemingly “random” (not actually true) reasons. And then there’s the weird interval between each string: all fourths, except between the 2nd and 3rd strings, where it’s a third. Wow, none of that is very pleasing or easy to understand by the mind’s eye! (Especially if you’re used to a piano).
Here’s a “what if…” that I figured out this week. This “what if” would probably have helped me when I started to learn the guitar…
A dash of history
A lot of experimentation went in to developing the piano keyboard as we know it, from the Greek “hydraulis” (world’s first keyboard), to the oldest pipe organs, to the harpsichord and so forth. From what I can figure, the design of today’s keyboard was settled around the 15th Century.
There are a lot of reasons we have today’s keyboard design, which I won’t go in to since I’m not an expert. I’ve posted a couple links below if you’re interested. Here’s what captured my imagination though. I looked at a picture of the hydraulis and noticed its completely flat keyboard:
The “What if…?”
There are reasons governed largely by the laws of physics that we didn’t end up keeping a flat keyboard like the one on the hydraulis. But let’s forget that for a moment. What if we had? In this imaginary “what if”, we’ll say that the piano sounds exactly the same, it’s just all white keys.
Each white key is a half-step above the next, so in twelve chromatic steps you go from C to C. It would look like this:

- Pretend the piano had no black keys
And so a C Major would look like this:

- A C Major Scale on the imaginary flat keyboard
And G Major would look like this:

- A G Major Scale on the imaginary flat keyboard
Notice a pattern? The interval between each note of the major scale doesn’t change, no matter what key you’re playing. That’s basic music theory, but visually on the imaginary flat keyboard, you can see how true it really is. A lot of times when we’re playing the real piano, we can forget this, because each key feels physically different on our hands, due to the raised black keys. But the pattern is always the same. On my imaginary keyboard, the major scale pattern is this:

- Pattern for a major scale in any key looks like this
Which brings me to the guitar…
The guitar is such a flat-keyboarded instrument! You do have to wrap your mind around the interval between each string, but the great news for a guitar player is that once you figure out a scale– major, minor, whatever– you now know that scale in every key. You just have to change where on the fretboard you’re playing. And, as long as you’re playing bar chords or “closed” chords (where you’re playing every string in a chord and no open strings), once you know a chord in one key, you know it in every key. This is the gift the guitar offers to guitar players.
If you’re reading this and you think “well, duh,” sorry to disappoint. It is a bit basic, I know. But when I was starting out on the guitar, I just couldn’t wrap my head around this… and I’m willing to bet there are others out there with the same problem right now.

At the end of this week, I’ll hit a milestone with my Key of the Week program: the first full cycle of all the major keys!
What exactly does one do with the key of the week? It’s really up to you. I’ve intentionally left this vague. The main goal is to frequently think about the key of the week on a daily basis, even when you’re not at your instrument. The longer term goal is to make each key more and more instinctive to play and use, so every key feels as free and obvious as “the people’s key”, C Major. Remember, no matter what technical ability you or I may posses, there’s always something else to learn.
