Q. How do I snap the best picture for the best results?
For optimal results hold your camera as close as possible to the line of sheet music. Do not include clef, key signature nor time signature in snap. Holding the camera too far away causes the OCR not to work as well due to low resolution of musical pixels. The auto-focus should work resulting in a clear picture.

Q. Why can’t I hear the play back on my iOS Device?
Because you have the mute on. Turn the mute off and you should hear stuff. Here’s a picture of the mute button.

Q. If you have to use the note editor to fix OCR errors, then why not just buy a Scoring App?
SnapNPlay will do most of the work for you. Editing the notes should be a quick and easy task especially since your sheet music is your guide on screen. As more updates are applied, there will be higher accuracy. Once you find the perfect distance to hold your camera, you will be able to have a line of sheet music ready in less than a minute.

Q. I snapped an image off my computer screen and it didn’t work so well. Why?
SnapNPlay is optimized for sheet music on paper. Images on the screen normally have low resolution and the light does funny things with my algorithm. Some times you will find sheet music on the screen works exceptionally well if it is high resolution or scalable like an svg or something.

Q. I printed sheet music from an image off the internet and your app can’t find the notes. Why?
Most images of sheet music on the internet do not have high enough resolution for the Optical Musical Recognition to work well. High resolution images or PDF’s that are optimized for printing are the best.

Q. Do I need to know how to read music to use SnapNPlay?
A. Kinda. SnapNPlay was created as a learning tool kit for those who are have an active interest in learning music. SnapNPlay will help you learn music by playing the tune so that you can hear it while learning to sight read from the printed page. If you do not read sheet music, but want to learn, buy the app! The editing process and animations will help you tremendously.

Q. Do I need to know what key my selection is in?
A. Yes. You can find the key signature on your printed music right next to the clef signature.

Q. After I snap my picture the SnapNPlay says it cannot find any notes. What is going on?
A. Be sure to hold the camera steady. Hold it as close to the sheet music as possible while including the line you wish to hear. SnapNPlay needs a clear picture to work from. If you’re drunk, sober up first, or ask a sober person to snap for you. If you got the shakes, try a tripod or a homemade vice of some sort.

Q. Sometimes the SnapNPlay misses a note. I can see the note displayed in the picture, but the note is not highlighted and does not sound in the playback. What can I do?
A. You can use SnapNPlay’s built in note editor to fix any notes that might have been missed in the analysis of the photo. Currently SnapNPlay cannot read some notation which may be more complex, such as triplets. Use the note editor to fix the playback and to deepen your understanding of music.

Q. My picture looks funny? What’s up?
A. The Musical SnapNPlay relies on auto-focus to work. Does your phone or tablet have auto-focus? If yes, is it working?  if not contact the developer!

Q. Why is this the only Musical OCR app on the market?
There is one in Japan called Gakufu. But it doesn’t play the music back. It depends on user interaction to play notes. It is very difficult to achieve high accuracy to appease the masses especially since it is difficult to control how the user uses the camera. Optical Music Recognition can take up a lot of memory and processing time too. SnapNPlay is a great start in this new realm of technology and it will improve over time. Your support will help a lot.

Q. What’s the difference between Optical Music Recognition and OCR?
Optical Music Recognition (OMR) is a type of OCR. OCR is a term used to describe recognition of characters in an alphabet. In music, the notes and various other symbols are the characters.
