Deep Breath – Mat Parrott

(3 customer reviews)


Master the most underused principle in all of mentalism.



Mat Parrott demystifies an esoteric mathematical principle first published over 50 years ago by Norman Gilbreath; The Gilbreath Principle.

Only a handful of the world’s most accomplished mentalists understand the power of this ingenious concept and how it can be exploited to create explosive demonstrations of power.

With it, you can:

  • Effortlessly predict lottery numbers chosen completely at random.
  • Sense the colours and suits of playing cards you’ve never seen.
  • Deal straight flushes to everyone at the poker table from a shuffled deck.
  • Divine words from books your spectator is thinking of.
  • Amaze anyone over Zoom by reading minds with Scrabble tiles.

The secret principle allows you to know, with 100% accuracy, information about a deck of cards (or stack of any items) mixed by a spectator. It allows you to create and perform miracles without the use of any gimmicks and without the use of any sleight of hand.

We believe so many mentalists never truly grasp the power of Gilbreath because they freeze up when they see the algebraic equations it’s traditionally taught alongside. The effects are astonishing but on paper they sound so damn complicated to achieve!

The truth is, the principle is actually really, really easy and Mat Parrott will prove it to you (without any algebra in sight!)

Deep Breath unlocks the previously unattainable, making Gilbreath accessible for EVERYONE.

Despite having its foundations in mathematics, there is NO MENTAL MATH REQUIRED whatsoever; Even a grade F math student can begin performing these impossible demonstrations within minutes!

Best of all, because this brilliant method is so under-utilised by performers, effects that apply the principle can be massive magician foolers!

Mat Parrott, author of BREATH, begins the tutorial explaining the concept visually and elegantly using poker chips of different colours. Within minutes, the entire principle will make complete sense and once grasped, there are no limits to the amount of effects you can create and perform with it.


The in-depth 105 minute explanation video includes five powerful, easy-to-do effects to get you started using the Gilbreath principle:

Out Of Breath: A spectator shuffles a deck of playing cards and cuts off a small stack. While your head is turned away, you are able to divine the colour of each and every card in the stack. Think Luke Jermay’s Colourblind using a regular deck of cards.

Poker In The Rear: Your influence will cause a spectator to deal every person at the table a winning poker hand from a deck that they’ve just shuffled! From the moment you hand them the deck, you never touch it again.

Booktest: A spectator deals numbers from a mixed stack of number cards to create a random page number. You proceed to accurately divine the word a spectator is thinking of from that page in a book. Works with any book, in any language.

Scrabbled: From a mixed bag of Scrabble tiles and in a fair procedure of free choices, your participant creates a word of their choosing. Against all odds, the word is accurately predicted in a very surprising and entertaining finalé. Great for virtual performances.

Lottery Prediction: A stack of numbered cards are mixed by the spectator and they deal six random numbers. Impossibly, they match the exact same numbers printed on a real lottery ticket that has been in full view from the start! Everything is 100% examinable.

Once you have completed watching the comprehensive explanation video, you will be able to understand and apply this versatile methodology to almost any stack of items: from slips of paper to poker chips, from playing cards to tarot cards and everything else in-between.

Its applications are endless!

    If you have a deep understanding of the Gilbreath principle, you probably won’t find anything new here, but if you are like me, and have heard of it and always wondered about its potential, I would highly recommend this video for you. Mat does a fantastic job explaining the Gilbreath Principle verbally and visually, without bogging it down with any math. He then goes into the effects. I will be putting Out of Breath in my repertoire right away. He then does what most videos don’t, which is show some basics on show to shuffle the cards, and a couple of false cuts and shuffles. This section is not going blow the minds of seasoned professionals, but if you are new to magic, this video does not leave you stranded with the phrase “use your favorite false cut or shuffle here”. Enjoyed every minute of it and it was well worth the money. Highly recommended!

    Brilliant. I still don’t completely understand the principle……..but that’s the whole point! You really don’t need to, the principle stills works regardless. Matt takes you through the basics & that is all you need to know. Excellent teaching along with a set of really effective routines. Highly recommended.

    This exposition of The Gilbreath Principle is an excellent attempt to make a complex mathematical principle available to the magic community without requiring we earn an academic degree in mathematics. The information here might even lead to the development of your own original magical application of the Gilbreath Principle. Highly recommend!
