The melodica or pianica is a wind musical instrument, more precisely with free reed.

It is similar in its operating mode to a harmonica, but unlike it has a keyboard, which can have a range of 1.5 to 3 octave octaves.

The sound is obtained by blowing into the mouthpiece of the instrument, located on the side of the keyboard.

The press of a button then allows the air to pass through the corresponding reed and obtain a note.
