A really useful guitar wheel for anyone who hates guitar theory!

I’ve struggled with the modes, like a lot of guitarists have off and on for some time and this wheel pretty much solves my headache!! All you do is set it to the key you want to play in and read the notes and chords off. Can’t believe anyone hasn’t thought of doing it this way before now. It might be useful for guitar teachers?. There’s some chord reference charts on the back which I didn’t need, but I can see how they might be useful to some people. The solo guide is pretty useful too. Great product!

Will improve both ear and playing skills

This gets beginner guitar players “tuning in” to recordings and will improve both ear and playing skills. If the player takes the trouble to learn the fretboard and the other 4 main Pentatonic “shapes” then so much the better.

Finally a way to learn modes that makes sense!

To set up my review, I’ve been playing guitar for nearly 40 years. I play everything from classical to light rock to hard rock to heavy metal. (You can find my stuff on youtube under JohnLogsdonMusic, if you’re interested). Anyway, I learned most everything I know by ear and studying up on tablature. Over that time I obviously picked up what all the notes are, many of the chords (though not all), and numerous scales. However, I couldn’t tell you what mode I’m playing in at any given time. I’ve learned how to find my way on the neck, but I don’t know WHY I’m playing where I’m playing on the neck … other than it sounds right. Well, I received the Mode De-coder today and I spent the last hour watching the youtube videos and messing about with the little wheel and all the diagrams. I put down a quick backing track that played 8 bars of C, then 8 of D#, then 8 of B, and finally 8 of E. I found that I was jumping in and trying different modes, hearing nuances I’ve *played* before but now was understanding what I was doing! It was pretty awesome. Next I started looking at the chord structures and found myself playing all sorts of things I’d never played before. Honestly, I’m just blown away. There are time when any artist gets stuck trying to come up with new song ideas and being caged into only knowing a handful of ways to piece things together doesn’t help. I just came up with three new rhythms using this tool that are way different than I’m used to, and that’s sparked some fresh creativity! All I can say is bravo! I tried many a different product over the years and found them to be confusing at best and frustrating at worst. This is the first time in all my years of playing that I’m starting to understand the modes. I know I still have some studying to do, but this is great stuff. HIGHLY RECOMMENDED!

…  you have freed my soul and helped me to improvise

Thank you VERY MUCH. . .I am learning the lead to this song. . . i followed a lesson with tab and played at a very slow pace and i have managed to play the first solo off by heart EVEN with my eyes closed. . .HOWEVER the second solo is so long and when broke down into small sections i was loosing the feel for the lead. . . So i decided i should really learn the scales. . Yes it was back to basics. . .i leaned the minor one very easily and your video was exactly what i was looking for to play it up and down the guitar as i was loosing the will to live following the tab. .. It was like writers block or something similar  . .  you have freed my soul and helped me to improvise . . i am off to practice. . .Thanks again. . .

Outstanding – you won’t regret buying it

Since others have written so eloquently and accurately about the quality of this item, I will merely say that having just received this, everything they say is correct. It’s a quality item that allows you to use a simple wheel mechanism to identify which style will suit what chord and it’s progression. On the inside there’s information on Location 1, 2 and 3 and the seven styles available, e.g. Ionian through to Lorian. On the back page there’s the chord reference chart. No space is wasted. It’s also a quality glossy paper and should last a while.

In addition, when you receive the item further material to help is also provided. For example, the mode de-coder is also on YouTube. It was watching this that made me decide to buy. Having talked through the benefits of the item, Sion Wyn Morris, the creator, then begins to play and it’s then that you see the guy’s love of music and the guitar shine through. I like people like that. I also like that people like that are willing to share their expertise and help make one’s own guitar development easier.

It’s a good price, a quality product and will help your development. Recommended.

Fantastic Sir!… This is a completely superior level

Fantastic Sir ! I got the Kirk Lorange slide rule from Australia in the 1980s and have used it ever since. This is a completely superior level (I have ordered one). Us ‘teach ourself’ types have spent years barking up the wrong or the same trees. I taught myself bass over years and focussed on scales and had no idea about modes or pentatonics! I even written and recorded many songs and played in many bands but it would have been nice to know this and something about chord progressions for jazz and funk and whatever. I did kart racing in the 1980s and it was like a secret society – no one would share any set up info and all before the Internet so I reckon it was same with music. Thx vm from Poole, England 🙂 🙂

The design and its implementation is nothing short of ingenious.

I’m primarily a pianist and a composer, but I do play the guitar with a sufficient enough level of skill and knowledge to appreciate and approach TMDC from the view point of a guitarist. Although you’ve created TMDC for guitarists; what you’ve actually invented is a musical tool that can be used by musicians in all walks of life.

My first use of the TMDC was with the piano, using it as an improvisational aid.  Without blowing my own trumpet, I would say that my knowledge of harmony and my improvisational and compositional skills are advanced.  I’m able to sit at the piano and make things up on the spot, in every key under the sun and in a multitude of styles. Even with my experience and knowledge I still found the TMDC an excellent aid.

No matter how much you practice and how much knowledge you think you have its always good to have a reminder there in front of you. It can also shake up playing  Say I’m playing in G# Dorian and because I’ve got TMDC in front of me, I end up using a min 9th chord were Id usually use a completely different extension in the same situation.  Although I wouldn’t use TMDC all the time with the piano, it’s without doubt an excellent and interesting tool for improvisation. It gives me an approach and option I didn’t have before. Thank you.

TMDC teaches guitarists how and where to play the modes, but the wheel on the first page of TMDC could be used by any musician, on any instrument, if they already have a basic knowledge of modes.

But now to the meat and bones; the TMDC was designed to be used as an aide for guitarists and here it really shines.
I think your design and its implementation is nothing short of ingenious. Having the ability to find each individual mode so easily at the three different locations is what makes TMDC such an extraordinarily powerful musical tool.

Most people, especially beginner musicians find modes daunting and intimidating but your device should give confidence to guitarists everywhere. There is of course a small learning curve to figure out the system, but after ten minutes I was happily noodling away all over the fret board.

Colourful simplicity with a hint of genius

Seriously… how has this not been done before?

I won a free guitar cable in a competition and enquired about the Mode De-coder at the same time as giving my details. Such a helpful chap I was given the Mode De-coder for free so I figured the least I could do was an honest review…

I have genuinely given myself headaches trying to wrap my admittedly overcooked brain around guitar modes for a what seems a very large proportion of my free time. What the Mode De-coder gives you is an instant access pass to the easy path.

I’ve spent hours going through some of my favourite works and finding new ways to go at them. Old songs come alive again and it just gives you the biggest smile. It’s admittedly not perfect since it doesn’t tune my guitar for me or make the tea… However it has accelerated my guitar skills and reduced my headaches!

When this ones finally dog eared (good quality materials so it’ll take a while) I’ll be buying another and I’d willingly pay five times the price! Thank you very much!

All that is needed is a basic understanding of chords and scales and the Mode De-coder does the rest

The Mode De-coder is a fantastically useful tool.  The instructions are easy to follow and the design is very neat and compact – perfect to slip inside a music folder or instrument case.  All that is needed is a basic understanding of chords and scales and the Mode De-coder does the rest.
It is equally useful for pianists; within minutes of using it I was improvising in all sorts of different styles and, as a music teacher, I can’t wait to use it to help inspire my pupils with their own compositions.
Finally, no more scratching my head when it comes to thinking about modes – if only I had this when I was still at university!!
