D) Music

Aim: To familiarize the user with musical instruments and their names, or to create musical pieces and save them.

How it works :


Upon entering this module, youll have to choose one of the two activities.

Note: You can choose to allow access to only one of the two parts ( see the "Preferences..." section of this guide ).

I. Identify musical instruments


The object is to click on the instruments name. A correct answer produces a pleasant sound, and fills the right-hand cylinder. The little hand shows that one must click to obtain the next instrument.

An incorrect answer produces another sound and empties the cylinder. One must try another answer.

A filled cylinder shows a winning message, an empty one, a losing message.

II. The Musical Keyboard


The following window shows up. On the left, a scale shows the sound level : dragging the button downward puts the volume up. ( One can drag the button by clicking on it with the mouse button and sliding the mouse while keeping the mouse button in the downward position.)

The picture with the instrument shows what type of sound will be produced. Clicking on it changes the instrument.

There are two ways to produce music notes; with the mouse or with the keyboard. With the mouse, all one has to do is click on the musical keyboard shown in the window. With the keyboard, there is a one to one correspondence between the key you strike and the note played. For example, the lowest C note is heard by hitting the letter q( the keyboard note on the screen is also lowered as if it were played ); the following D note corresponds to the letter w, etc. This is shown in the following pictures.

The user may want to save his piece of music by using the upper right-hand commands :.

The buttons are, in order : start, play, rewind, forward, stop. To record, you must at first click on the start button. Then, you play the sequences of notes. To end, you must click on the stop button. The play button now shows up green instead of gray. To play the recorded piece, you must at first rewind it and then play it.

To save the piece of music as a document, select "Save" from the "File" menu in the menu bar at the top of the screen or hit the command key and the s key at the same time. Youll create a new document.
