Store listing

By Happy Penny Games, from Google Play
Description by Happy Penny Games Written by the developer, not by AppBrain. Click to read.
Feel justified pride by striving to grow from no musical knowledge or experience to sight reading piano pieces*. You need a piano or keyboard to practice on, or just sing along and keep up with the accompaniment if away from your instrument!

Note: I can make the app more useful for you if you drop me a note happypennygames@gmail.com. Unfortunately "uninstalled" is not enough information to go on!

This app provides a confidence building curriculum of daily exercises of 15 minutes so you have a simple, structured, path with tangible milestones and a great accomplishment that will impress yourself and others at the beginning, middle, and end of your journey.

* Get your A.R.T. (accuracy, rhythm, and tempo) score with real time feedback! (requires MIDI connection to piano)
* Infinite, new exercises
* Classic songs and repertoire mixed in to play for others (Twinkle, twinkle; happy birthday; we three kings)

Curriculum:
Level 0-9: The very basics- start from middle C and end with C major scale, two hands
Level 10-19: sight reading intervals & the 6 octave grand staff & key signatures
Level 20-24: chords! 3/4 time
Level 26-29: 6/8 time

Future ideas:
Level 30-39: Leaps
Level 40-49: Sixths! Stretch that thumb and pinky!
Level 50-59: Sevenths and 8ths
Level 60-69: Finger crossings
Practice key signatures, dynamics, and increasingly challenging & fun rhythms in every level.


*Note: This app is not making any promises or guarantees of achieving a certain level of personal performance, as proficiency depends on many factors including instruction that one might obtain outside of the app.

** Multi-day free trial, all content unlocked**
Discover if it's right for you before making a one time IAP (and since this option doesn't exist yet- you can be using the app until it does :D ).

Features may be subject to change, including removal, and only available in latest version of the app, which may not yet have been distributed by Google through your app store.
