MusiChords
An Android app - combining a musical ear trainer and a chord dictionary
About this App
Purpose
This app combines a musical ear trainer and a chords dictionary.
The ear trainer can be used to either train your relative pitch (identify intervals between two notes), and your ability to recognise a chord by ear. You hear an interval or a chord, and have to find the correct answer from a list of options. You can customise this list, and create and save your own exercises.
The chord dictionary is for a quick lookup of a chord. Just select root note and chord from a drop down, and the app shows you a list of notes, chord intervals, midi keys, and a visual representation of the chord on a piano keyboard.
Motivation
After building my guess-the-chord game with React.js for web, I wanted to build something similar as a native Android app. I've used it quite a lot, and my ability to recognise chords has significantly improved. Just play a few rounds whenever you have some spare minutes.
Tech
The app was built with Android Studio using Jetpack Compose (written in Kotlin).
