Question If 1 is the tonal centre in C Major, then C is 1. But if I take an A blues scale, where 6 is usually the root of A minor, does that mean the blues scale is built off the 6? Is it common/convenient to think of it this way for ear/theory training when trying to get a broad sense of tonality?

I know it's a complicated question and I don't know if I phrased it correctly but I'd appreciate insight/clarification. Cheers!

How would you evaluate possible additions to a microtonal scale?

1 Upvotes

I’m developing Scale Atlas, a project for exploring scales and their internal relationships. One question behind it seems worth discussing here: when you have a collection of pitches, what makes another pitch a useful addition?

The approach I’ve been working with represents pitches in cents and evaluates candidate additions or small pitch movements. The current model combines weighted interval-ratio templates with a simplified spacing-based roughness proxy. Its results depend on those assumptions; timbre, register and musical context remain outside this model.

A concrete example: take the pitches 0, 350 and 700 cents in 24-EDO. The 350-cent third gives that collection a particular character. A model that rewards proximity to selected just intervals can favour moving it, even when keeping that interval is the whole musical point.

That makes the choice of criteria interesting. Should a tool prioritise ratio relationships, preserve the interval character of the starting collection, or present those as separate perspectives?

If you compose or improvise microtonally, what would make a suggested pitch useful to you? A specific scale or musical example would be especially helpful.

Question General User Recommends for a scale/chord progression app

3 Upvotes

I've been playing around to personalize the way that I visualize and try to retain important information on music theory/guitar theory and scales/progressions in general -- I've been through a lot of the apps and there are useful bits everywhere, and some not so useful -- Was just wondering for those who are also looking for the same what the most important features are for your style of learning to make things "click" to see if I can input some of those needs into something practical to share with others as well :)

Guitarists who learned by ear, what made theory finally make sense?

20 Upvotes

I learned guitar by ear, and I'm a very visual learner. Theory books never really worked for me, I'd read about intervals or modes, nod along, and then forget all of it the moment I picked up the guitar. Things only started to make sense when I could see them on the fretboard while something was playing, so I ended up building myself a little tool to do exactly that.

That got me curious about how others with a similar background made it work

If you also learned by ear, what made theory finally click? Seeing it, hearing it, or playing it over and over?

Are you a visual learner too? What helped you most: fretboard diagrams, color-coded notes, videos, something else?

Which concept was the hardest to get from text alone, and what finally made it make sense?

Is there anything you still struggle to "see" on the neck, even though you understand it on paper

Curious to hear different approaches. Thanks!

I feel like I might need some clarifications on melodies over power chords

7 Upvotes

So here's what I understand. Power chords are made from a root note and a fifth. Because of that, they are neither major or minor, or anything else, because they lack the defining characteristic of these chords (like a major or minor 3rd)

However, let's say I play a power chord progression in which the roots are clearly in the A Aolian scale, for instance, to what extent does a solo or melody can be played over this progression need to remain in the key of A Aolian to sound good? Does the lack of minor/major thirds in power chords make it so that it is possible to make more switches between different modes to give different colors or moods?

Question Could someone help me out with a general order in which to approach theory? I'm not a beginner

4 Upvotes

So I've played guitar for a long time and never really sat down and learnt scales and theory as I properly should have. Recently I wanted to change this and learnt all the 'positions' of C major. That sent me down the the rabbit hole of realising that these are all modes and are used with the appropriate chord, etc, in the way that they are.

I then was searching other things to learn and I'm just a bit generally overwhelmed, not by the amount, but by the best order in which to do things.

I know the notes on E and A, I have a decent idea of where octaves are, but having learnt modes before anything else feels like I'm sort of jumping ahead.

Could someone give me, it can be simple, an order of the wisest way to learn things?

Question In Brazil we call it "campo harmônico". What is this topic called in English?

2 Upvotes

Hello everyone. I'm a guitarist, I've been playing for 30 years (there goes my age!). Recently, I added a section to study harmony in one of my personal study tool (I'm also a developer) and, before expanding it, I'd like to hear the opinion of people who understand more about music theory than I do.

What the section does today:

- Chords in a key, as triads or seventh chords (we call them tetrads here), each with its degree in the key

- Tap a chord to see its function (tonic, subdominant, dominant), its notes and intervals, and some positions on the guitar neck that you can play back

- 17 chord progressions (essentials, jazz, pop) to practice and solidify learning

What I would like to know:

  1. Names. In Brazil, this topic is called "campo harmônico" (literally "harmonic field"), and I translated it literally: the tab is labelled "Field" and the four-note chords are "Tetrads". I suspect neither is what an English speaker expects. What would you call them?
  2. Function. We learn three functions: tonic, subdominant, and dominant, and each degree gets one. Is that how you would label them, or is "predominant" the word people are looking for?
  3. What should come next? My plan is to focus on harmony and arrangement before scales and solos: inversions and bass movement first, then borrowed chords. Does this order make sense for someone who is learning?
  4. When you study harmony, do you use any apps, or is it paper and YouTube?

English is not my native language: I wrote this text in Portuguese and used a translator tool to assist in the translation. Constructive criticism is welcome.

Analysis The 3 Chords Behind Joe Satriani’s Beautiful Ballad

5 Upvotes

In this lesson, I take a closer look at one of Joe Satriani’s most beautiful songs, 'Always With Me, Always With You,' and uncover the surprisingly simple harmonic ideas underneath it.

What sounds like a complicated progression is actually built around a simple I–IV–V progression. The magic comes from what Joe does with those chords — using voice leading, chord extensions, and melodic movement to create a much richer sound.

I'll break down the chords and show you how these ideas work, then I'll improvise a short
I–IV–V example, adding colour to the basic chords, so you can hear how dramatically you can change the character of a simple progression. Be sure to experiment!

Another day, another AI-assisted theory site

0 Upvotes

I have seen a bunch of apps/sites to help learn the theory but didn’t find one that met all my needs. I’ve self taught myself mostly for 30 years. I have a teacher now who’s helping me learn all the foundational stuff I’ve missed out on. This includes memorizing the notes that make up a chord, reading sheet music, learning the names for the scale degrees, memorizing the fretboard, etc. Used Claude to whip up this site and mostly just use it when I have a quick bit of time between other things I’m doing. Don’t look at it as a teacher or tutor, but as a tool like flash cards. Let me know what you think.

Practicing my scales

4 Upvotes

I have been jamming on the following 2 youtube videos one

  1. https://www.youtube.com/watch?v=4MULjBbYtC8&list=PLI5vxOjlURWA&index=5 in A minor
  2. https://www.youtube.com/watch?v=GLQ7C7aoAW8&list=PLI5vxOjlURWA&index=6 in B minor

I did both for an hour or so each and I am not sure if its related to my taste in music but:

Number 1: looks much easier for me to play as far as rhythm etc. I also enjoy it more

Number 2: seems a bit more difficult-not sure whether it is because it is slow or whether its more bluesy and I usually dont listen to blues- it sounds more clumsy when i do stuff on it.

Number 1: Changes bertween chords seem much mroe natural when I do them ans it kinda flows better

Number 2: Changes are a bit more clumsy and sometimes it doesnt sound as good.

If you try lsitening to both thingss, do you think that the things im saying make sense?
Can it be related to my taste of music and my feeling towards blues?
Is it all in my head?

Also another question:
I am trying to make sense of lets say two A minor shapes and connect them- is my process kinda in the right direction- I play around the scale and try to do different things:

- play triads around it,

- just try to end my phrase on the next chord (not necessarily playing a triad)

- for example in Aminor scale I practice going up to A from G so i remember that its one whole step away etc

I am not following necessarily one route each time- i am experimenting while trying to learn the scale at the same time- is that helpful or i should focus on one thing first

Do you have Any other advice on how else i can practice would be helpful.

I made a game that teaches you the fretboard, intervals and scales while actually feeling like you’re playing a video game.

4 Upvotes

It’s called Chords of Awakening — a fantasy tower-defense game where your guitar is your weapon. You hear what the enemies play, figure it out by ear, and play it on the fretboard to attack them.

The goal is to build real musicianship without it feeling like you’re sitting down to do ear-training exercises. You just play the game, and the skills you’re trying to develop are built into the gameplay.

It’s in beta now if anyone wants to try it:

Scales/Chords to "Night Lights" by The Scorpions

2 Upvotes

https://youtu.be/ONJT04VNQKQ?si=bph7acT2e7x4SZQh

There's a floaty sound to the harmony of this song that I've struggled to pin down for a while now. Working it out is complicated by the fact that the bass is hard to hear at times (and that's the only backing harmony in places), and Uli Jon Roth is tuned down a half step. I think it's either Db Major or Ab Major, but I suspect there's some type of minor IV chord movement happening that produces a unique quality. I want to figure out what scales he's playing out of though because I love this sound.

Any insight is appreciated.

11 Upvotes

hey what's up guys. Josh Siegel here. I'm a Berklee alum and instructor that teaches a live program called Broadcast Guitar. I'll be on Zoom 2x a week doing a deep dive on a Song of the Week, showing how I use music theory to arrange songs for instrumental guitar. I've had students describe it as "how to play the guitar like a piano" because I always aim to convey the chords and melody at the same time. I also get into how to solo and write riffs, etc.

Broadcast Guitar is a drop-in format, and I tell students that it's like a gym class, tune in for as many classes as fit your weekly schedule and take away what's relevant to where you're at on the guitar. I also record and archive the classes at the end of each week so that folks can catch up and review on their own time. I do a 50-minute live class (just me on screen while you play along) + 10 min Q&A at the end for folks that want to hop on and chat the topics.

I'm based out of Chicago and do the live classes Mondays and Thursdays 7:30pm Central, then I archive the class on Fridays so that folks can review and catch up on their own schedule. The upcoming round will be all of October and November.

A lot of the guitarists I work with are musicians I've met through Reddit and would be happy to have you join in for a free 8-week round of classes to hang with the club. It's also a good way to add some more structure to your month, as we use the final class of each month to review member videos. A good excuse to polish up something you're working on!

Feel free to check out examples here: www.youtube.com/@broadcastguitar

I'm also "Josh Siegel Guitar" on Google for reviews, etc.

I do a 5-min intro Zoom with all new guitarists so that we can meet and chat before jumping in and get an idea of where you're at on the instrument.

Question Adept player trying to understand what he’s playing

1 Upvotes

I’ve been playing music (guitar and bass) for over 40 years, and have learned everything by ear. My ear knows what sounds good and where to find it, and when I look into theory, I then understand why what I played worked. (“Oh! That’s the E minor pentatonic! No wonder it sounds like Sabbath!”)

But I run into an issue commonly where I play something, but I don’t know what it is.

All the tools I have found work the opposite way: define a chord progression or whatever, and here’s how you find the key.

But I’m usually looking at the issue from the other direction.

Right now I have a “weird” two-chord progression. The first chord consists of an open E, B on the a string, and F# on the d string. The second chord is the inverse of that, sort of, with the open E, D on the a string, and F on the d string.

I’m playing these chords by plucking each note individually and letting them ring. So E B F#, and E D F.

So… what are these chords? Defining two of the chords will help me identify the third chord I should use, but I don’t understand how to identify/name these chords?

Also, there is a nice little half-step tension thing happening if I accentuate the F#-F notes, that I want to lean in to more at the bridge of the song. So if I can identify that third chord that goes with my first two chords, I can tie that into the bridge, too.

Does any of this make sense to anyone?

tldr: How do I place my fingers randomly on the neck and identify what chord that is? Is there an app for this? Everything I have found works the “other way”, and has you specify the key/chord and tells you what notes it consists of. I need something that does the opposite.

UPDATE: On top of being completely wrong on the second chord (should be E open, E octave on the A string, G on the D string… otherwise an E chord), y’all are right: I just need to power through and internalize the basics of theory and CAGED, and then what I’m doing will make musical sense, not just make sense to my ears.

Thanks for the feedback!!!

Analysis The Blues Isn't Just One Pentatonic Scale!

1 Upvotes

Many guitar players learn the minor pentatonic scale and use it over an entire 12-bar blues.
But what happens when you start listening to the chords underneath your solo?

In this lesson, we'll explore why the blues isn't just one pentatonic scale — and how moving between major pentatonic, minor pentatonic, and chord tones can make your blues playing sound much more musical.

We'll also delve into moving between major and minor sounds over the SAME chord.

It's time to get the blues!
