The earliest evidence of the harmonica dates back to 3,000 BC, when the Chinese Empress Nyn-Kwa had her maids play a reed instrument known as the sheng (“sublime voice” in Mandarin). However, it was not until 1830 that the instrument adopted the form that we know today. Since then, this instrument hasn’t stopped growing in popularity, in part due to its affordability and small size.

What is a harmonica exactly?

This small wind instrument presents a design usually based on plastic, metal, or wood. It has individual reeds for each musical note. Those same reeds must vibrate to make the instrument sound. This is achieved by sucking or blowing in one or several holes of the harmonica.

It is so small that it can usually fit in the palm of your hand and is very easy to carry around. Combined with the folk music revival of the 1960s, this has contributed – and still contributes – to its unwavering popularity. The appearance of harmonica stands has made it even more useful, as you can now play it at the same time as other instruments.

If you play the guitar, a harmonica might just be what you’ve been waiting for to continue to grow as a musician.

These instruments offer a series of advantages that we have listed below for you:

What keys does a harmonica have?

Before we get into the types of harmonica available on the market, let’s talk about their pitch. While the most common harmonicas come in C major, there are many more:

  • Harmonicas in low octave, double octave, or high octave: these harmonicas have octaves below or above the standard octave and are used to achieve a higher or lower timbre. They are generally labeled as L or low, LL or low, and H or high.
  • Sharps and flats: While this key is also available in major and, as we will see below, minor tones, it is best to rank it separately. This is because many people mistakenly believe that there are no harmonicas in sharps or flats. This isn’t true at all, and Lee Oskar instruments are a perfect example of this.
  • Minor keys and custom tunings: You can find a wide range of harmonicas in minor keys, but the most common remain those of natural minor scale or key. Once again, the Lee Oskar instruments are famous for this. As we briefly mentioned earlier, you can also purchase models with custom tunings.

How should I clean my harmonica?

These instruments need continuous care to stay in tune and good condition. This is even more important if they are made of wood, as saliva can deteriorate the material relatively quickly. In order to extend the life of your harmonica, you are recommended to brush your teeth before playing and to avoid sharing it with others. In addition, you have to clean it thoroughly from time to time:

  • It is best to dismantle the instrument for optimal cleaning. All you will need for this is a screwdriver.
  • Make sure you treat each part with care to prevent damage. Have a place to put the different parts during cleaning so you don’t lose them.
  • Clean the comb or central mechanism with a brush. Try using a knife or any other sharp tool to remove any remaining dirt.
  • Brush it again. You can put alcohol on the brush for better results. For the metal parts or reeds, add a spoonful of baking soda to a blend of water and vinegar.
  • Clean the harmonica with water. Before you put the instrument back together, make sure to let it dry thoroughly. Otherwise, all your cleaning work will be in vain.

How can I tune my harmonica?

Keep in mind to your instrument needs to be clean to stay in tune. That being said, the reeds tend to go out of tune with time anyway. You can correct this with soft sandpaper whenever possible by reducing the size of the affected reed until it goes back to the desired key. Place something thin between the comb and the reed to avoid over-tuning.

You will have to be extremely careful when carrying out this process. In addition, you must constantly check whether or not you have reached the key you’re looking for. Keep in mind that this is helpful if you are trying to lower the pitch. You can try to manipulate the reed if you need to go higher, but you will most likely have to buy new reeds. Luckily for you, they are relatively inexpensive.

Learning Level

Professional or high-quality instruments can be costly, and it doesn’t make much sense for you to spend a fortune on your very first harmonica. Start small and work your way up. The time will come for you to buy a top-of-the-line Hohner.

Music Genre

This might not be the most important factor when you’re starting out. It’s all about learning, and you can always adapt your harmonica to the style you want to play. However, you will have to shop around for the right key once you start progressing with your instrument. The possibilities are almost endless, but we have designed the following table to give you a head start:

If you want to You should use
Play blues A chromatic or a Blues Harp diatonic harmonica.
Play along pop or rock songs A diatonic harmonica like Pro Harp or Lee Oskar.
Play jazz A chromatic harmonica like Kmise.
Playing American folk music or music from your region A double-reed or a diatonic harmonica. The Marine Band is very typical of this style.
Play in an orchestra or classical music A special or a chromatic harmonica.

Type of Harmonica

This factor is directly linked to the two mentioned above. The harmonica you choose will depend on the genre you want to play. However, there are various types for each style, so you should also consider your skill level. If you want to play blues, for instance, you can do so with a chromatic harmonica – especially in the third position. Note that this requires a slightly more advanced technique.


The materials directly influence the sound of the harmonica and its playability. Wood produces a warmer tone, typically found in blues. Plastic offers greater versatility but reduces the personality of each key. Wood will require more protection against humidity while plastic doesn’t, making it ideal for beginners.

In case you are going to use it as an accompanying instrument, do keep in mind that the same harmonica isn’t necessarily suitable for any song – even if it fits into the right genre. A harmonica in C major can generally only be used in that key. You may be able to widen its spectrum if you are experienced and know how to play in different positions, but it certainly isn’t easy.

As we mentioned earlier, most harmonicas are in C major. If you know how to change positions, such as to the second position, you can use your instrument for songs in G major as well. Luckily for us, the best harmonics on the market are available in all kinds of keys. Remember that harmonicas in C major are a great option for performing solo pieces.


You can play the harmonica on its own, but it also offers a unique touch to your songs as an accompanying instrument. Its melancholic, sweet, and even strident sound provokes all kinds of conflicting emotions in those who listen to it. Regardless of your skills as a musician, the harmonica is always a useful and entertaining instrument to master.

However, it is important that you are familiar with it in order to choose the most suited to your needs. As you now know, the genre you want to play will determine the type of harmonica you should invest in. Keep in mind that each variation requires a specific technique. You should also pay close attention to the manufacturing material of the instrument, as well as its key.
