• AirTap! tuning (& Erik Mongrain interview!) •



Used by Montreal acoustic genius Erik Mongrain to facilitate the virtuosic ‘lap-tapping’ techniques of AirTap!, an oldskool viral favourite (uploaded way back in 2006: YouTube’s early days). Like playing piano, bass, & drums on the strings – all at the same time…


The interval structure matches our ‘classic’ Gmaj shape from Standard tuning (‘3-2-0-0-3-3’). Although 5 of the strings are altered, the changes are all small, with more raised than dropped: Mongrain’s barre-finger slappery requires firm tension on both sides to ring out crisp. Read on for some fascinating direct input from the man himself!

Pattern: 4>3>5>7>5
Harmony: Fmaj | 1-3-5-1-5-1

The performance that launched Erik Mongrain to his (likely inevitable) acoustic guitar stardom arrived to the web via an exuberant performance on French-Canadian TV (AirTap!). You can also listen to the piece in 3D-realistic ‘binaural‘ sound here (headphones required for full effect).


He expanded on the origins of his ‘lap-tapping’ style (which he estimates as being ~75% improvised) in an Interviewtion profile: “I saw a street musician playing like that here in Montreal when I was around 18-19, [and] figured I’d try the technique on my own…Developed my way to do it, and there you have it! No technique feels natural when you start though”.


  • AirTap! (TV) – Erik Mongrain (2006):

“Nirvana and grunge music…is what got me into guitar playing. I wanted to emulate all of it! I never took any lessons: learned everything on my own, and by watching and listening to guys that were better than me.” (Erik Mongrain)

I emailed Erik to learn more about his tuning explorations: “This has been a gradual process, through learning countless open tunings and experimenting with them. It’s an intuitive thing, sometimes my mind has to work for it, and sometimes it just pours out. Inspiration is strange – I always feel like I’m just a ‘vessel’. Like the great Michael Hedges said, ‘the secret of discovery is extremely sweet’.”


“More specifically: if, say, I wrote a tune in FACGCE: I’ll always try to see what happens if I just change 1, 2, or 3 of the strings [e.g. to AirTap‘s FACFCF]. This is convenient, seeing as it gives a whole different tint to the chords and their colours…and, for the most part, most positions and left-hand fingerings won’t change all that much.” (n.b. Read his tales of video-game inspiration in my Equilibrium writeup – and also check out this curious AirTap ‘cover’ by Miku Hatsune: “the official [virtual] anthropomorphism of a ‘Vocaloid software voicebank’ developed by Crypton Future Media”.)


  • AirTap! (Binaural) – Erik Mongrain (2009):

“I’ve always found the world we live in very noisy and alien. Music puts my mind in the ‘off position’ to some degree, but gaming fully absorbs me, and allows me to escape…Game soundtracks help inspire the music I write even today…For me, it doesn’t matter where it is from: if it’s genuinely creative and harmonious music, it will have an impact on what I write.” (Erik Mongrain)

There is more than one way to find new color!”)
