...I'm cleaning up some of my Nix expressions. Read the article for more
context.

7a7c29d46c Restore default view to Overview
I often debug by changing the values of State.Model in the State.init
function. I usually revert these these chage; this time I didn't.

d84d0000e0 Correct all G_sharp pitch classes
I incorrectly modelled all of the G-sharps in my application as belonging to the
G pitchClass, which resulted in a strange bug where vieChord printed "G minor
Root position", but the Piano highlit a G minor.

I checked the other accidentals, and it looks like everything is properly
classified.

ae31090a46 Remove unused Msg's
I'm sure this app contains more unused code. I would like to find some Elm tools
for detecting and deleting dead code, but this isn't my current priority.

My current priority is dogfooding this app until I find it genuinely useful for
myself.

a059c32403 Display "Get ready..." message before practicing
This is a temporary solution. Ideally I would like to handle this with the
following:

- Show the flashcard for a chord shortly after beginning a practice session
- Display a small 3...2...1... countdown timer immediately after beginning a
  practice session

I need to dig more deeply into Elm's Time module and subscriptions to better
understand how to properly solve this problem. In the meantime, please tolerate
this short-term solution.

d134db700f Support a FlashCard before showing the notes that comprise a chord
My much anticipated feature: first prompt the user for a name of a chord, then
show the user that chord.

Cascading changes:
I changed the "Tap to practice" overlayButton's opacity from 30% to 100% because
pausing when showFlashCard is True causes the two piece

TIL:
You can batch Elm Subscriptions using the Sub.batch function.

What I haven't learned yet:
How to best handle rotating screens for mobile devices (i.e. portrait
vs. landscape modes). In time...

What's left?
- Support sound
- Support a fine-tune section of the preferences
- Support tablet and web browser variants
- Ask users for the "I chord" instead of asking "C major Root position"
- More styling (of course)

f92fe97aff Create Tailwind module
Moving the UI.tw function into Tailwind.use. Creating and consuming some
functions like Tailwind.if_ and Tailwind.when to make it easier to conditionally
style some of my components.

7b2163d804 Ensure the overlayButton is truly h-screen and w-screen
Now the "Tap to practice" button fully covers the screen.

- Dropped support for a Piano direction (for now)
- Using w-full and w-1/2 for piano key "length"

2fe6d7a10c Responsively size UI
TL;DR: scale down UI for non-mobile devices.

I pulled the screen resolution for my phone, the Google Pixel 4, off of the
internet. I created a device profile in Chrome to develop this application
specifically for my phone. To my surprise, when I opened the app on my phone,
many of elements that looked good in Google Chrome, looked askew on my phone. I
needed to troubleshoot.

Here's how I did that:
I used Tailwind to responsively color the bg for each breakpoint to see if my
device was sm, md, lg, xl (according to Tailwind's breakpoint
terminology). After reading Tailwind's documentation and comparing their
breakpoints with my Pixel 4's width (i.e. 1080px), I figured that my device
would be lg. It's not; it's md, which I confirmed by using ngrok to load
localhost:8000 on my phone and see that the background-color was
"md:bg-green-600".

I'm still unsure why my device is not lg, but knowing that my device was md
was enough to fix many of the styling issues. My current theory is that while
my screen's resolution is 1080 wide, the pixel density affects the media query
for the breakpoint.

74ebb8e869 Set the selectedChord to Nothing when setting a key
This helps us avoid showing a chord from a key that the user did not whitelist.

11b140b6ae Highlight root note of each chord
Refactor the Piano component to highlight the root note of each chord. If this
makes things too easy, I can support this as a preference.

Also:
- Reduced the number of keys that the piano displays and increased the key
  thickness to reclaim the space
- Preferred using Tailwind selectors instead of inline styling where applicable
- Call List.reverse on the keys to ensure that the top-most note is a lower note
  than the bottom-most note

TODO:
- Support showing only the name of the chord and not just the notes that
  comprise that chord
- Rewrite the function that generates the chords for a given range of notes
- Consider supporting a dark mode

9e855f7427 Create Overview for Learn Piano Chords
Since I've published this, I should include an Overview page to orient potential
users. This Overview could be better -- as could many things with this app --
but it's a start, and I'm seeking small wins.

82ebc0ad19 Debug unresponsive button press for selectKey
Observed problem: Tapping "C major, A minor" key, which LPC sets by default,
does not unset it.

Bug: handleClick passed the relativeMinor Key but the default value in
State.Model is the C Major key. We would toggled b/w [Cmajor] ->
[Cmajor,Aminor], and because toggled checked if either Cmajor or Aminor was
present, it was always true.

Solution: Check relativeMajor to set toggled.

441fe3e32e Tidy app
Now that I have a deployed an MVP of my app, I am tidying things up to support
the next phase of development.

TL;DR:
- Moved application Model-related code into State module
- Moved each View into its own module
- Deleted unused ChordInspector component
- Deleted unused Msg's, {Increase,Decrease}Tempo
- Deleted misc unused code

ddbd7e2ef5 Ignore Main.min.js
The elm2nix expression builds my code as Main.min.js. As such, I changed my
index.html to require Main.min.js instead of elm.js. When I run elm-live now, I
make sure that I output Main.min.js as well. I need to gitignore this to exclude
it from my repository though.

f0803547e4 "Chord Drill Sergeant" -> "Learn Piano Chords"

closely to the functionality as I can imagine.
