Want to buy a kalimba but noticed that there are instruments with very different numbers of tines? Is there a big difference between a 17-note and a 21-note thumb piano? How can you make the right choice when it comes to the number of keys on your African-rooted musical instrument?
Having had the opportunity to play more than a dozen kalimbas over several years, I’m well placed to explain the differences between thumb pianos depending on the number of tines they have.
When it comes to kalimbas, there is no perfect number of tines that suits everyone. The number of keys on the instrument should be chosen based on the future player’s musical goals and skill level.
It’s helpful to look at what each version offers:
- Fewer than 10 tines
- Between 10 and 15 keys
- 17 tines
- 21 notes
- More than 21 keys
So, after reading these few lines, you’ll have a very good idea of the kalimba with the perfect number of notes for you—or for a loved one, if you’re thinking of gifting one.
Now let’s look at the ideal number of keys for a thumb piano.
Why are there so many kalimbas with different numbers of tines?
The kalimba is a musical instrument similar to a classical piano, which is why it’s often called a thumb piano. Just like on a piano, each tine corresponds to a single musical note. So, the more keys a kalimba has, the richer and more varied the melodies it can play.
On the other hand, more tines usually means a more complex, more “advanced” instrument—often heavier and bulkier, too. The whole idea behind the kalimba is that it’s simple to pick up, compact, and easy to carry around. So the goal for any thumb piano player is to find the right balance between these factors to get the best playing experience. Too many tines can be frustrating because the layout feels more complex, while too few can make the kalimba feel overly basic. You can hit the instrument’s limits quickly, which may lead to boredom.
That’s exactly why there are so many different kalimbas available. It’s also worth noting that the number of tines isn’t really tied to overall quality. It would be a mistake to assume that more keys automatically means better craftsmanship. Now it’s simply a matter of exploring the options to find the thumb piano that suits you best.
Small instruments with fewer than 10 tines
Kalimbas with fewer than 10 tines are generally considered pocket-sized, travel-friendly instruments. They’re very small, usually under 4 in (10 cm) long, but they’re also fairly limited in terms of musical possibilities and resonance. That said, they can be wonderful companions you can slip into a pocket and take anywhere. If you’re a globetrotter and space is a real concern, a thumb piano with fewer than 10 keys can be a great option. Just keep in mind that, in most cases, accessories such as a tuning hammer aren’t included.
This type of instrument can also be perfect for introducing young children to music. In fact, for little kids, giving them a kalimba that’s too complicated can be counterproductive. All of this is discussed in more detail in this other article on the age at which it’s possible to start playing the thumb piano. If you’re planning to give this instrument to a child, we strongly recommend reading that guide.
Between 10 and 15 keys: medium-sized thumb pianos
With between 10 and 15 keys, the kalimba’s potential expands considerably. You have enough notes to play a large number of familiar melodies with more than respectable accuracy. If you feel that a thumb piano with more keys might be too complicated for you, this can be a great middle ground. The same can be true for some children who are ahead of the curve musically. The older kalimba model developed by Hugh Tracey in the 1950s had 15 keys, which is further proof that this format is a solid option.
However, there are relatively few kalimbas with this exact number of tines compared to other thumb pianos. As a result, you may have fewer choices in terms of wood species or design than you would with a 17-tine model, for example. It’s worth keeping in mind when you’re ready to buy.
Is 17 notes a good idea for a kalimba?
The 17-note or 17-tine kalimba is currently the benchmark model in the world of thumb pianos. It’s the best-selling option, with the widest selection and the most consistent availability. Looking for a particular type of wood, such as maple? You can find it. Want an unusual design, like a cat-shaped stand? No problem. Interested in a transparent acrylic kalimba? You’ll have plenty of options there as well. It’s also often around this tine count that you’ll start finding models with a resonator box, which can create fun effects using two sound holes on the back.
In addition, the 17 keys let you play a wide range of melodies. Because this is the most common kalimba format, the vast majority of sheet music, tablature, and tutorials are dedicated to this tine layout. That’s why, in my opinion, any budding player hoping to learn the thumb piano is usually best off choosing a 17-key instrument. Sure, 17 keys can feel like a lot for a beginner, but you can deliberately ignore the outer tines at first to make the instrument feel simpler.
Finally, the price difference between a 17-note kalimba and one with slightly fewer keys is not that significant. That makes sense: 17-note models are produced in much larger numbers than 15-note models, for example, and shipping costs are the same. Plus, the essential tuning hammer and sets of stickers are very often included with the instrument.
Is the 21-tine mbira suitable for everyone?
Many kalimba beginners also wonder whether they should get an instrument with 4 extra keys, bringing the total to 21 tines, compared to a classic 17-key model. It’s true that adding just 4 notes doesn’t sound like it would make the thumb piano much harder to learn. In practice, though, it can feel noticeably different.
To go from a 17-key to a 21-key kalimba, the four additional tines are added not on the outside, but in the center of the instrument. That’s simply because even smaller outer tines wouldn’t be able to vibrate properly due to their reduced size and would therefore produce little to no sound. Those four extra keys significantly change the tine layout compared to a 17-key kalimba. That means most sheet music and tutorials written for 17-note instruments won’t easily carry over to 21-tine thumb pianos.
However, if you already have musical experience (for example, on another instrument), if you’re naturally creative, or if you plan to play by ear, a 21-note kalimba may be ideal for you. There’s a wide selection available, and the price difference between a 17-note and a 21-note instrument is often only a few euros, shipping included. On the other hand, if you plan to use your thumb piano mainly to play well-known songs by following sheet music or tablature to the letter, a 17-tine model is usually the better choice. If you’re still unsure, check out our detailed comparison between 17- and 21-tine kalimbas. You’ll be much more confident after reading it.
Sanzas with a chromatic range of more than 21 keys
If you’ve browsed the available sanza or mbira models—alternative names for the kalimba—you’ve probably noticed that some instruments feature 20, 24, 34, or even 42 tines. Because the length of the tines limits the instrument’s range—the span of sounds it can produce—any tines beyond a 17- or 21-tine model mainly add the “in-between” notes (sharps and flats). These thumb pianos can then play all 12 semitones found in Western music and are referred to as chromatic scales.
These are clearly not instruments for everyone. Aimed at a more professional audience, this type of kalimba is much more complex and is not a good choice for beginners. In addition, the finer tuning they require demands a bit more dexterity. They’re best reserved for experienced musicians who know music theory and have solid musical experience. That said, they’re also often luxury instruments made from fine or precious woods. They may also come with extra accessories, such as an upgraded protective case or an amplifier, which can be a great option if you really want to treat yourself.
Treat yourself to a kalimba that suits you
The number of tines is an absolutely crucial factor when choosing a kalimba. It’s important to select the right number of keys to get the most out of the instrument. Now you know everything you need to make a confident choice, whether you’re buying for yourself or picking out the perfect gift for someone else.
However, finding a high-quality kalimba that produces beautiful sounds isn’t always easy. This type of instrument is still relatively unknown to the general public and remains quite exotic. It would be frustrating to end up with a disappointing instrument from a non-specialist seller. To solve this, the Instruments du Monde store offers a finely crafted 17-key kalimba that suits the vast majority of players, with free shipping included.
