The Irish Session Harp has four Unique Advantages for Irish Music over all other harmonicas:

That's very gratifying, but on a personal level I became more and more frustrated with a single glaring issue ALL harmonicas have with playing Irish tunes. The harmonica is a linear instrument with a single point of contact: your mouth moving along a horizontal playing surface. That’s fine for tunes which move progressively up or down the scale in easy steps. However when you get rapid repeated wide intervals between notes, the construction of the harmonica becomes a real problem! You end up jumping around all over the harp with your mouth; at high tempos this is frankly impossible to do fast, smooth and clean.
Irish dance music was formed over centuries by players of other instruments: mainly the fiddle, Uillean pipes, flute and whistle. They are NOT constructed in a linear mode. For them, it’s no problem to jump a fifth, a seventh… even an octave, and back to a pedal note in rapid succession. For example, on a fiddle it’s merely a matter of rocking your finger over a few millimeters to an adjacent string and back to get a smooth, fast wide-interval jump: so easy! Because these rapid wide note jumps have such a cool sound and are simple to play on the traditional Irish instruments, they’re used widely in Irish tunes of all types: reels, jigs, hornpipes…
Up till now there’s been no easy way to play tunes with these fast wide jumps on the harmonica. The only possible route has been a technique known as ‘tongue-switching’, where the player gets the wide intervals by playing them from the left and right corners of their mouth and flicking their tongue side to side. However this is a very difficult technique to master, and requires one to be an expert with a tongue-block embouchure. As a result there are very few players who are any good at it. And even then if you listen closely, the notes can sound a bit blurry. That’s because, since the tongue is being used to actually isolate the notes, it can’t be used to tongue selected notes to get a sharper attack when you want to. Using the lipping embouchure plus the button on the Irish Session Harp allows this flexibilty of expression.
It’s constructed with two rows of buttons, each in a different key. Irish button boxes come in two formats: with the two keys a semitone apart (B/C or C#D), or in the two main keys for Irish music (D/G). The D and G scales in the D/G box have many duplicated notes, but use different bellows actions for the two rows. Thus Irish button box players have the option of playing a tune all on one row, or crossing between the rows to grab the same notes in a more convenient location whenever they wish.
It’s this “Crossing Rows” concept that gave me the inspiration for the Irish Session Harp. Instead of playing two different harps in Paddy-Richter tuning to cover the Irish repertoire (one in G and the other in D), the Irish Session Harp combines them both in one harmonica. On the G/D version you have the G Paddy-Richter scale with button out, and the D Paddy-Richter scale with button in. The D scale is a fifth higher than the G. Thus with a simple press of the button, you instantly get a fast, smooth fifths interval!
This new type of twin-key construction in one harmonica overcomes the problem of the single linear scale. Instead of having to jump around with your mouth on one harmonica to get wide note intervals, you simply keep your mouth in the same place and press the button. It’s SO much faster, smoother and EASIER! Having this new capability (literally at your fingertip!) suddenly makes all those great Irish, Scottish, American & Canadian fiddle tunes with fast wide jumps accessible to us harmonica players! It’s a real game-changer.
Although overcoming this problem of rapid wide-interval jumps was the main reason I created the Irish Session Harp, it has two other huge plus points as well. Here’s a breakdown of the four key advantages it has over all other harmonicas for playing Irish tunes:
The observant ones among you will notice that in hole 7 of the slide-in scales, the draw note has been flattened by one semitone. Using the G/D harp as an example, the C# of the D major scale has been lowered to C natural. This gives a correctly pitched slider jump when the harp is being played in the primary slide-out keys of G and Am, which both have a C natural in their scales.
It doesn't affect playing tunes in D with the button in, because they will all be based in the lower two octave up to hole 6 draw, the B5 note. This is the highest note found in 99% of fiddle tunes - because it's the highest note fiddle players can reach in first position.
YOU WILL UNDERSTAND THE LOGIC OF IT ONCE YOU START PLAYING ALONG WITH THE NOTEFLOW TUNES. So please overcome your initial consternation and accept my assurance that it's actually a big PLUS for the Irish Session Harp, which will become clear once you start learning tunes on it.
If you need that missing C# you can bend 7 blow D a semitone down to get it – so the note IS still available. Likewise for the slide-in A scale on the LowD/A version of the Irish Session Harp: the missing G# is available by bending the 7 blow A note down a semitone.
However there are a couple of other tunings that are also popular for playing Irish tunes: Easy Third and Solo Tuning. These also work great as Irish Session Harps! That’s because the big advantage of having two primary keys in the same harmonica apply to Easy Third and Solo just as well. They will also benefit from being able to play fast wide-interval jumps and the option to choose an easier alternative position for tricky phrases.
See the diagram for how Easy Third and Solo Tuning look in the G/D version of the Irish Session Harp (click to enlarge image). (Note relationships between the two scales are the same in the LowD/A Version).
