Why should kids learn the harmonica? Because it's fun!

And also:

• It’s cheap
• It fits in your pocket

• It’s cool and fun - the original iPod!

• You can play scales and tunes over three octaves
• You can read music with it
• You can also play rhythms with chords
• You can also play melodies and chordal rhythms at the same time
• You can also play pairs of notes simultaneously and using different intervals including octaves
• It’s a good introduction to music - it equates to the white notes on the piano
• It appeals strongly to boys – it’s not sissy
• It’s easy to play, you don't need to use fingers (manual dexterity can be hard for young children)
• It sounds great right out of the box
• You can learn to play it chromatically (all the sharps and flats). Children mostly don’t get to this stage so we play it modally to access C major, D minor (dorian), E minor (Phrygian), F major (Lydian), G major (mixolydian) A minor (aeolian), B minor (locrian)  
• You can play the Blues – where it is best known
• You hear it on adverts and tv theme tunes all the time
• A lot of bands use the harmonica as part of their show
• There are a thousand harmonica performances viewable for free on YouTube.

Plus it will even lead to work if you want it to; there are many people who play music in bands and who teach and write about music as a full time or part time living.

A child who starts an instrument in primary school could easily be earning a living from music aged 18 if they put their mind to it, and having musical skills is a job for life in any country.

The social aspect of learning a musical instument, the teamwork skills you learn, the sense of community you feel, the friends you make, the travelling it gives you - it's all good!

I wouldn’t say the harmonica is better than recorder, ocarina, ukulele or anything else but it’s got a great deal in its favour. Alright, let's be honest - it's way better that all these other instruments!

The harmonica is the highest selling instrument of all - one company alone, M. Hohner, has been making 30 million harmonicas a year since the 1930s. The Chinese factories are much bigger again.
