This program streamlines the monotonous parts of guitar practice.

• pick a pair of chords and play them as many times as possible in one minute.
• record your scores to get feedback on which pairs of chords you need to work on
• pick a random pair to play
• weighted random: more likely to choose pairs with lower high scores

• Enter chords you know in the tab titled 'My Progress'
• Navigate to the 'Chord Changes' tab and select a pair of chords on the grid
• Click 'Start Timer' to begin a session. First it runs for 3 seconds to let you get ready, then it runs for 60 seconds.
• Enter the number of times you played the chords
• View your results after submitting your score
• Buttons in the Chord Selection screen change color depending on your high score
• Return to the 'My Progress' tab when you learn more chords or to view a table with information about your play history

• Add more features to the chord changes practice
  • add a decay attribute to each chord pair - the longer it has been since you played it, the more you are advised to practice it
  • add a stats screen / widget where you can view a graph of your recent sessions
  • add sounds to the timer start and end
• When I learn more about guitar and music theory I'll add some more features to this.
  • tools to practice chord progressions
  • scale practice
• Add a metronome feature
• Clean up this repository so it includes the fewest files necessary.

I use regular expressions to verify that chords are valid. I don't actually know what all of the different kinds of chords are so the regex is incomplete. For beginners like myself this is not really a problem. More advanced chords like diminished, suspended, or something complicated like 'G#m7b5' will not work. I will update it in the future. I'll probably just make some variable or file containing all chords and use that instead. I'm not sure if RegEx is the best tool for the job. I just wanted to mess around with it.
