Before you start playing it is pretty obvious that you need a harmonica and typically what you need if you play blues is a diatonic harmonica. This is the 10-hole version that is quite common in blues, rock and among troubadoures. Some people think this instrument is a toy but nothing could be further from the truth. Diatonic harmonicas from serious brands are serious instruments but suprisingly cheap compared to other instruments. There are a few things you need to know before shopping around for your harp. This article aims to give you a good start.
First of some basic stuff, what you are looking for is a Richter tuned, major diatonic harmonica. Most often you can leave out the “Richter tuned” part when you search for a harp but you want to be sure it is a major diatonic. Most diatonics are major diatonic. Some brands offer other version such as melodic minor and harmonic minor variants. These are more suitable for playing folk music and melodies than blues.
Choosing the key
OK, so now you know the type of harmonica you need, another thing to decide is what key to choose. The key of the harmonica is which scale the harmonica is tuned to. A C-major diatonic harmonica is tuned to the C-major scale. It is basically a small piano with the black keys removed (and a few of the white keys as well). So what key to pick then? First off, it doesn’t matter what key you use when you play by yourself and learn to play. All keys work the same way. However if you play with other people you need to be in the right key. Also if you choose a harmonica that is tuned to a very low key it can be more challenging to play at first.
Very high pitched harmonicas can also be challenging to control. What you want in the beginning is key somewhere in the middle of the range. Traditionally G is the lowest key and F (or possibly F#) is the highest key. Nowadays many brands offer keys outside this range such as low F, or even down to low low F. I would recommend a C-major harmonica to start with. This puts you in the middle giving you a very workable harmonica without “extra” challenges, also a C-major harmonica when played in 2nd position, which is the go-to position for many blues harmonica players and what you normally learn first, is in the key of G which works reasonably well for most guitar players.
If you choose to buy more than one harmonica I would recommend an A-major harmonica as well as this plays in the key of E in 2nd position and is also a nice key when you play by yourself. In fact if you get the following keys you are pretty much set for most situations: C, A, G, Bb, low F and D.
Choosing the brand
So, now you know what type of harmonica and the key to buy so now we have to choose a brand. There are a lot of brands out there and in the end it comes down to what you like and what suits your playing style. I make these recommendations based on my own preferences and what I use and have used. If you ask somebody else you may get other recommendations. One thing though, you basically get what you pay for. A cheaper harmonica tends to be less durable and in some cases not as well set up out of the box.
The list below is in order of preference from my point of view.
Generally speaking I recommend Hohner, their harmonicas have been the standard for many blues players for a long time. This is no accident, other brands may have gained ground at Hohner’s expence during the last few years but for me Hohner is still my choice.
The Marine Band Deluxe was the Hohner flag ship product for a number of years, it is an updated version of the classic Marine Band with a better sealed comb and reed plates that are screwed on rather than nailed. They play very well out of the box and also lend themselves well for repair work and custimization. The tuning of this harp works very well for blues and the chords are beautiful.
The Crossover is an updated version of the Marine Band Deluxe with even higher precision and bamboo composite comb that does stands up very well against moisture. As with the delux it is very maintainable and plays lamost perfectly out of the bos. The tuning is slightly different so the chords are not as smooth compared to the delux but it works over a wider range of keys and may therefore be a better choice if you not only play 2nd position blues but other styles and positions as well.
Before Marine Band Deluxe and Crossover this was the go-to-harmonica for many blues players. An often copied harmonica and for good reason. It works very well out-of-the-box. It has a partially sealed pear wood comb. You may experience som swelling of the comb with this model which is a draw-back but it is not too bad. The reed plates are nailed to the comb which makes maintenance of this model a bit more cumbersome than the Deluxe and the Crossover.
The three harmonicas above are far from the only options but reallt what I prefer. Here are some other options to consider if you either don’t like these three, prefer platic combs or can’t get hold of them for some reason.
Hohner Golden Melody is a nice harmonica that is a bit thicker, it plays very well but is tuned to equal tuning which works better for melody playing so chord heavy music is not its strong point. Hohner Pro Harp is a plastic comb harmonica quite close to the Marine Band Classic but very maintainable as it is part of the Hohner MS system. Hohner Special 20 is a plastic comb version of Marine Band, many people like it but I never made friends with it. Lee Oskar is a very custimizable and maintainable harmonica with lots of spare part options. They work better for melody heavy music due to their tuning. C.A Seydel & Söhne 1847 Classic is a really good harmonica that feels semi-custom to begin with which is quite special, the only draw-back is that it is a bit pricey.
If you would like to order harmonicas online I can truly recommend Thomann for europeans. Excellent selection, good service and fast deliveries. For full disclosure, I am a Thomann link partner.
