What Clefsight is, and isn't
- For reading, levels 2 to 7. From a first tune over a simple left hand to advanced pieces, about Henle grades 6 to 7: 419 pieces in the library, each with 3 or 4 versions from right-hand melody to as written, and your own MusicXML or MIDI files simplified the same way.
- New music to read. Fresh sight-reading written for what you read well and what you don't, and 36 free sight-reading exercises at levels 1 to 6 to print or play.
- Marked like a teacher's copy. After a take, wrong and missed notes are circled, early and late ones ticked, and the bar to practise is bracketed. How grading works.
- Not for songs from the charts, video lessons, an acoustic piano through a microphone, or a keyboard plugged into an iPhone or iPad.
