Sometimes, simple is better

The photo above shows exactly what you will see. If you click on a key on the keyboard, the note will sound and will show on the staff. If you press the up or down key on the staff, the note will play and the key will become grey. The range of notes is 11 white keys to both the left and right of middle C. There is no help and no directions—and none are needed. On the left of the photo above you see a movie reel with the key signatures. You can click and drag to rotate the reel to select a different key. If you do, the staff will show the appropriate sharps or flats. As you press a key on the keyboard, the notation reflects the way that key press would be shown in the selected key. For example, if you selected the key of G, then F is sharp. If you play the white F key, the notation shows as F natural. I never quite figured out key signatures before seeing them displayed the way this app does.

I took piano lessons 65 years ago and bought this app to improve the link between seeing the note and mashing the right key. This app does it perfectly.

What I’d like to see: 1) more keys—full piano, 2) ability to force display on a selected clef. For example, the B below middle C always shows on the Treble Clef, despite the fact one can often find it displayed on the treble clef.

Easy to use, great tool for learning note placement on scale and keyboard

I am an older learner, trying to teach myself piano. At this age, memorization is not my strong suite. With both visual and audio, bold graphics and clear sound using my iMac running OSX Sierra, the app was just what I needed to progress with the basics, and no doubt it will help me learn even more as time goes by. For anyone with visual limitations (I am legally blind) the graphics are clear and the white on black is beyond wonderful for me, with a clutter-free interface. A user can progress up and down the scale or choose to click on a key on the virtual keyboard to see the name of the key, see its position on the scale, and clearly hear its sound. I bought another app I thought would be easy to see, but it had a very limited function (no treble clef even), really collorful but limited to a very small range of notes. The song-playing-and-learning apps simply are too fast for me at this stage, and many have smaller graphics. I love it! Thank you to the developers and I encourage them to keep updating so it works with future OSX versions.
