Gonzalo has done a wonderful job of creating an onscreen keyboard that the user can customize to their location and needs.
By clicking on the small "Q" at the top of the screen, the user can set the on-screen keyboard to show the letters and numbers of the corresponding notes on the QWERTY keyboard. This is very helpful for XOs without a touch screen. It should help eliminate the confusion children who have had piano lessons encounter when, for example, the Qwerty C key plays the musical note of E or the Qwerty B key plays the musical note of G. Users can easily see the Qwerty keyboard relationship with this version running.
Clicking on the next button, "DO," makes the keyboard show the solfége syllables as used in most Latin American countries and some European countries, where the 7th note in the scale is sung as "SI."
For countries, such as the USA and and some European countries where the 7th note is sung as "Ti", you simply click on the "TI" button!
Of course, some people will want the letter names of the notes, and clicking on the "C" button will magically switch to the letter names of the notes.
Finally, for purists (best on a touch screen) all note names can be eliminated by clicking on the "X," giving just a plain, standard keyboard.
Other small, but important details are the inclusion of the enharmonic names of the "black" keys, for example, A# and Bb are both marked on the same key because, on a keyboard, they sound exactly the same.
Thirty-three instruments are available for choice, and while they don't sound exactly like the instruments they represent, they are close enough to make it interesting to try different sounds.
All in all, a wonderful tool for use in the music classroom and everywhere else!

I think this activity is a way to insert the children to the music.
