Fatter Harmonica Sound

The diatonic harmonica is a small instrument with many inherent limitations. It is up to us as players to get a good sound. The key to getting a fatter harmonica sound is the take advantage of the design of the diatonic harmonica. This is also where the tongue blocking technique comes into play to make use of different techniques. In this article I will show how to fatten up a lick so that it sounds bigger.

From thin to fat

The thinnest and most basic sound we get out of the harmonica is when playing clean single notes. This is often where we start and perhaps how we learn a new song or riff. The basic melody is clearly heard when playing like this. However, for blues this is not the most exciting sound. Getting a fatter harmonica sound is al about understanding where to apply techniques and still keep the basic melody of the riff.

Fatter harmonica sound example 1

In this case we are going to take a riff from the beginner blues harmonica riffs article previously published here. It is the boogie inspired 2-bar riff.

Original version.

By adding tongue slaps to the inhaling notes 2 2 3 4 and the exhaling 5+, and exchanging the 5 draw for an inhaling chord and finishing off with a octave tongue split that plays 6+ and 3+ in unison with a tremolo the riff gets a whole lot more exciting. It is still the same basic melody but the techniques used offer more volume and excitement.

In this example we use the 1-bar riff from the same article above.

To get a fatter harmonica sound here we leave the 4+ alone, switch the 4 to an inhaling chord and play the 5 and 6+ as dirty notes. Once again the basic melody is kept but it sounds bluesier and fatter.

Try it!

Now you try it yourself on riffs you already know. Use tongue slaps, pull slaps, side pulls, octave splits, dirty notes, chords etc as you see fit to get the sound you want.

Harmonica Tremolo or Vibrato?

When people talk about different techniques I often find there is a bit of confusion when people don’t agree on definitions. The part where I hear and read this most often is regarding harmonica tremolo and vibrato. In this article I will give you the definitions on how I think about these techniques.

Harmonica tremolo definition

The tremolo effect means that the volume goes up and down periodically. You can do this either with your breath or by cupping and opening your hands. This can be used either on single notes, dirty notes or chords. Sometimes people call shaking their head and going between holes tremolo but I prefer to call that a shake to separate it from a “proper” harmonica tremolo. The shake can of course be done with a tremolo but they are not the same thing.

Vibrato definition

A vibrato on the other hand changes the pitch of the note(s) rather than the volume. However sometimes people think they are continously changing the pitch when in fact they are changing the volume. This is where some of the confusion arise. As with the shake the vibrato can be combined with a tremolo.

Making it more complicated

Actually, the shake technique where you moreve between two notes or between dirty notes belong in the vibrato group rather than the tremolo group since the frequency content changes. Some people may also argue that the a harmonica tremolo done by hand technique changes the frequency content of what you hear and then it could be placed in the vibrato category. All in all Iike to think about what my intentions are and call it a harmonica tremolo if I am actively changing the volume, a vibrato if I am actively changing the pitch and a shake if I am shaking my head.

Octave Split on the Harmonica

Playing single notes on the harmonica is an important skill but is not always the coolest sound on the harmonica. Fortunately tongue blocking offer a number of ways to get more out of your tones. One of these ways is to use the octave split to get more sound out of the harmonica.

What is an octave split?

Octave split is quite simply playing two single notes one octave apart simultaneously. To the listener it will not necessarily sound like two notes (if the harmonica is properly tuned that is). Two notes played at once will be louder than one note and that will definately help when you are playing notes in the high range.

How to do it

In principle, splits are very easy. You simple play one note out of the right corner of your mouth and another note out of the left corner of your mouth. Your tongue will block the holes between them. To do this you need to control your tongue so that it is just wide enough to cover the holes between notes. You will also need to make sure that your mouth has the right size to block out any holes outside the holes you are aming for. Once again I will mention the Filisko Tongue Block Trainer which is a great tool for practicing this.

Not all splits are created equal

To get a proper octave split you will need to know where to find it. The exhale notes are quite easy, simply block two holes to get an octave. 1+-4+, 2+-5+, 3+-6+, 4+-7+, 5+-8+, 6+-9+ and 7+-10+ are all true octaves.

For the draw notes it is another matter. On the lower end some octaves are true octaves when blocking two holes and some are fake octaves. Going up higher you will need to block three holes to get true octaves.

True octaves:

  • 1-4 (two holes blocked as for the exhale notes, know as a 4-hole block)
  • 3-7 (three holes are blocked, known as a 5-hole block)
  • 4-8
  • 5-9
  • 6-10

Apart from the 1-4 all other 4-hole blocks are fake octaves. The 2-5 is quite common and is a root note (2) with a minor seventh on top (5), a very bluesy sound. The other 4-hole draw blocks can be used, just be careful about if it is the sound you want.

The fact that you need to adjust from 4-hole to 5-hole blocking can be quite challenging when playing the upper range. However it is well worth the effort to get the extra power in your notes.

Make it your own!

If you are not already using octave splits I suggest you start praticing it to get the most out of your upper range and add to your sound.

Side Pull Technique

This week we continue looking at techniques that change the presentation of the notes played. Tongue blocking offers quite a few techniques. In this article I focus on the side pull technique.

Side pull description

The side pull technique is very simple in principle but can be difficult to execute. As the name implies the tongue is pulled sideways to let air into the harmonica. More specifically part of the tongue is pulled sideways to go from a full block to a standard tongue block position.

The main difference to a tongue slap or a pull slap is that the tongue never leaves the face of the harmonica. It is simply the position and/or width of the tongue that change. This means that there is no chord played as part of the technique giving it a less aggresive sound.

Performing the technique

To peform the technique you start by fully blocking the harmonica and apply breathing pressure. Move your toung or change the with of your tongue on the right side to open up the hole to the right of your tongue. You will need to be in very good control of your tongue to do this correctly as the movement is very small. Use a tongue block trainer to practice. See the two steps below.

The result is a single note that start very abruptly as the air pressure has built up behing your tongue. All that air is now forced passed a single reed on the harmonica.

When to use

You can basically use the side pull technique any time you would consider a tongue slap or a pull slap. It is especially good to use if you feel the other two techniques sound to harsh or aggresive.

Dirty Notes on the Harmonica

When playing harmonica which notes you play are of couse important but how you play them is just as important. In previous articles I have described techniques such as tongue slap and pull slaps which are ways of presenting the notes differently from the simplest form of presentation. In this article I will introduce dirty notes which is a technique that can be used by both tongue blocking and puckering players.

Short definition

Dirty notes are simply notes that are colored by another note which is not the pitch you intend to play. This gives it a grittier, dirty feeling that works very well for blues. If you think that a riff sounds too clean, then this technique may be just what you are looking for.

How to create dirty notes

The principle behind dirty notes is very simple. You simply play the note you want to play and widen your mouth ever so slightly to let a little bit, maybe 20%, of the upper adjacent hole in. So, if you play hole 4 you widen your mouth to the right and let a little bit of hole 5 in. I like to think that I smile a little with the right side of my mouth. You can use a tongue block trainer to see what goes on.

Tongue Block Trainer

The result should still sound like hole 4 but with a bigger dirtier sound. Remember you are not aiming for a two hole chord, hole 4 must be dominant. Listen below for an example.

Hole 4 on a C harp going from clean single note to dirty note back to clean single note.

How to develop the technique

To develop the technique I suggest you play hole 4 inhale and the very slowly and conciously widen your mouth to the right. When you hear the effect happening, experiment with how much of it you want. Too much will spoil the effect. It should sound dirty, precise and intentional. It is not just sloppy playing, it is a deliberate choice!

When to use

Dirty notes can be used very freely when playing blues, especially when playing something aggresive. To make the effect stronger it is a good idea to play some clean notes every once in a while. Also of you are going for a smooth sound then dial back on the dirty notes.

Now I suggest you try it out for yourself and hear how much bluesier you can sound. Don’t forget to sign up below to get the Welcome package and exclusive articles!

Pull Slap Technique

Expanding your vocabulary of techniques is a great way of creating more possibilities for your self as a blues harmonica player. In this article I will explain the pull slap technique. I feel it is a great addition to let you shape the sound you get out of your riffs.

Pull slap vs tongue slap

The pull slap is building on the tongue slap technique and it can sometimes be hard to distinguish between them when listening to a recording. The sound will be a little bit sharper and a bit more staccato than the standard tongue slap. The reason for this is that the air flow is fully blocked and an internal pressure is built up before the tongue slap is performed. This pressure is the reason that the chord part of the tongue slap is a bit sharper and very pronounced. The staccato feeling comes from when the holes are first fully blocked before the pull slap is completed.

As you can understand from the explanination above it is a very good idea to first pratctice tounge slaps before mving on to the pull slap. It is also a quite simple extension as the only thing you do is covering all holes with your tounge first.

When to use

You can basically use the pull slap whenever you would use a tongue slap and can be a great way of slightly varying the sound. Sonny Boy Williamson II was a master of this technique. You can hear it in “Born Blind” for example.

I suggest to add this technique to your arsenal begin working it into your riff vocabulary. You can never have too much technique!

Tongue Slap Technique

One of the things I like about tongue blocking is the variety of different techniques available. For me it the embouchure that gives me the best ways to sound bluesy. One of the first techniques to learn as a tongue blocker is the tongue slap. In this article I explain how it is permormed and the sound to expect.

Basic tongue slap

The tongue slap technique can most easily be explained as a short chord played immediately followed by the highest note played as a single note in the tongue blocking embouchure.

To do your first tongue slap follow these steps:

  1. Place your mouth over holes 2,3 and 4. You can include hole 1 if you like.
  2. Place your tongue over holes (1), 2 and 3. Now you are in position to play hole 4 in the tongue blocking embouchure. To make sure that you have positioned everything correctly you can try inhaling or exhaling. You should now hear only hole 4.
  3. Without breathing lift the tongue from the harmonica.
  4. Initiate an inhale chord by breathing in.
  5. Quickly place your tounge back over holes (1), 2 and 3 blocking them completely. You should now hear hole 4 on its own.

Going from step 4 to step 5 should be extremely quick. You do not want to hear it as a chord followed by a single note. You are looking for a single note that is preseeded by a sharp heavy push. This is extra prominent when playing through an amplifier. You can use the Filisko Tongue Block Trainer to see what goes on inside your mouth.

Below is a simple riff played both with and without tongue slap.

Original, without tongue slaps.
Same riff but with tongue slaps.

When to use

The tongue slap technique is great to use to spice up very simple riffs, it will make them sound bigger and more interesting. I would say that you can use the technique quite extensively but make sure to mix it up with at least a few “unslapped” notes. Too much of the same thing makes it uninteresting.

If you are not already using tongue slaps I suggest that you incorporate it in your playing for that extra punch in your sound.
