About a week ago an idea for a new song popped in my head. I started writing and came up with a verse pretty quickly, and the chorus followed shortly afterwards. As I love talking about music and creative processes and such, and I’m never sure how I write songs when people ask me about it, I decided to take notes about this last one, and explain how I did it. This is by no means the only way to do it. Or, for that matter, the only way I do it.
This should be easy to understand even if you don’t know music theory, as I don’t really use a whole lot when I write (I don’t know all that much myself, anyway). Also, I’ll try to explain the concepts I do use.
The spark for this song was a title and a topic. The title was “Who are you?” and the topic was the feeling of not knowing someone anymore after they change or we discover something about them we didn’t know.
Just minutes after the spark came, a melody popped in my head. Note that I wasn’t thinking about any scales or chords or anything like that. A melody popped in my head and I just needed to write it down before I forgot it.
The first thing I did was to figure out in which time signature the melody was (it’s in 6/8). A bit more on that below if you don’t know music theory. Once I found out it’s in 6/8, I went to http://music-explorer.org and found the notes for the melody, then wrote down the following (at the time I couldn’t notate it properly):
1 2 3 4 5 6 A E A B 1 2 3 4 5 6 1 2 3 4 5 6 B A B C 1 2 3 4 5 6 B A A E
This is a simple visual representation of the melody. The letters are notes, and the numbers are used to count the beat. This is how it sounds:
If you don’t know music theory
If you have no idea what the 6/8 above means, listen to the drums and see how you can count together with the drums, in groups of 6. You should be able to count four groups of 6, and each group should feel like a short phrase, as in it makes sense as a group. If you tried to count in, say, 4, each group of 4 would be random notes, and wouldn’t naturally follow the music.
Look at my made-up graphical representation while you listen to the music and see if you can make sense of it. See how in the last group of 6, the second and fourth notes are not aligned exactly with a number! That happens in the music, too.
If you don’t know music theory: what are chords?
A chord is three (or more) notes played at the same time. Often, one starts with a melody and then adds chords to it. The chords have to have common notes with the melody they accompany.
If you want to try some things, go to http://music-explorer.org, type the chord into the “Highlight chord” box, and press Enter.
If you do know music theory
For some songs I try to write more intuitively, more “from the gut”. This is one of those. In these cases I don’t try to find the key or the scale I’m using, and I don’t think of which chord is the I, or the iii, or whatever. I just try several things until I find something I like.
Adding chords to the verse
As we can see in the visual representation I made, the first notes are A, E, and B. Now, which chords contain at least some of those notes? I tried a couple, and I decided that I liked Aadd9 (which is made of the notes A, B, C#, and E). Because the second bar (the second measure for you Americans; if you don’t know music theory, I mean the second group of 6 beats) doesn’t have any notes, I kept the chord.
For the third bar I liked how Cmaj7 (which is made of the notes C, E, G, and B) sounded. That matches B and C, but not A. That’s fine. For the last bar I only matched E because I went with Cadd11 (I had the impression that I’d like the chord to be another kind of C, and I liked how Cadd11 sounded there; Cadd11 is made of the notes C, E, F, and G).
This is the end result, playing the chords once in the beginning of each bar:
Rhythm and groove
The rhythm of the guitar and the drums was just a placeholder. I wanted the rhythm to be a bit more sophisticated than that. Long story short, after playing a bit with it I ended up with this version:
If you listen closely you’ll hear that in the last bar I added a variant of the Cadd11: it’s Cadd11/E.
Adding a bass line
After I got the guitar chords, I added a bass line. For each bar we know the chord being played, and we know which notes it contains. So, the bass plays one or more notes from the chord (could be the melody, too, but I usually pick from the chord notes).
The first two bars have Aadd9, and in this case I kept it simple and only played A (the root note, ie. the one that gives the chord its name). In the third, the chord is Cmaj7 and I decided to play C, again the root. In the last, the chord is Cadd11, and I decided to play F and E (the 11th and the major 3rd respectively).
Note how the melody, guitar, and bass don’t always play at the same time. Instead, they “weave” the song together.
For the chorus I did something similar: started with the melody, added some chords I liked (by looking at the notes in the melody), then decided the rhythm for the guitar and the drums, and finally I added a bass line. I don’t always work in this order, but it worked for me for this song.
I ended up with the chords Cm7 (comprised of C, D#, G, and A#), C#maj7 (comprised of C#, E#, G#, and C), and Am (comprised of A, C, and E).
Final version (verse + chorus)
This is not the whole song because I’m going to add something more: most likely some kind of outro, a bridge, or maybe space for a guitar solo. But the final version of verse and chorus plus the repetitions I expect to have in the final version are here:
I hope this was useful and easy enough to understand! If you have questions, you can contact me on Mastodon (email@example.com), where I post a song every Monday, with a short explanation of something interesting to notice when you listen to it.

Last Friday I gave a talk about “Listening to music”. It all started after a conversation in which I was trying (and failing) to explain what the “progressive” label meant in “progressive rock” and “progressive metal”. I figured the only way was to show the same piece of music with simpler and more complex arrangements. This is the blog post version of that talk.
The idea of the talk was twofold: first, give a better idea of the possible differences between a straightforward rock song and a more complex rock song. Second, to show examples of musical decisions that make a song sound different, so it’s easier to spot why we like the music we like. It was never my intention to suggest that more complex music is better (everything has its uses), just to see that songs sound like they do because of a number of decisions made when writing and recording it.
Through the talk, we take the chorus of a song and rewrite it to be a simple as possible, and then we make changes until we’re back to the original.
This is the original version of the song (just the chorus, really). It’s not quite progressive rock, but it certainly has similar elements:
Now, we are going to rewrite it to sound as straightforward as possible.
This is a completely rearranged version of the same chorus, in the most straightforward way that still sounded like a song someone could write:
Compared to the original, this should sound much more familiar, safe, and stable. Many things have been changed to reach this version. In the following sections we’ll undo those changes one by one and we will end up with the original version.
First change: chords
The straightforward version uses “power chords”, which are simplified chords used often in rock, punk, and metal. I prefer full chords, so the first change is just that:
The difference can be quite subtle, especially with this computer version. You can compare just the guitar in one and the other here:OLDNEW
Second change: bass line
If you pay attention to the song as is stands now, the bass is simply repeating the root note of each chord being played. The result is that the bass “supports” the guitar, making the sound of the chords fuller, but not much more. Instead, let’s make a more playful bass line, using some of the available notes in the chord (instead of always the root):
The only difference is the bass. Compare the old bass line to the new one:OLDNEW
Third change: rhythm
The next step is to change the rhythm. The common rhythm most pop and rock is built upon is 4/4, but I’m fond of 6/8 (a rhythm that sounds somewhat like waltz, and it’s often used in ballads). This difference is somewhat big because all instruments have to adapt:
Compare to the version in 4/4:
🛈 Example of song in 6/8: Somebody to love by Queen.
Fourth change: strumming
The first version in 6/8 has a very simple groove: it simply marks the chords being played and little else. Hence, we’ll change the guitar to have a nicer groove. The bass rhythm will be a variation on that, but while at it we’ll also changes the notes. Thus, both guitar and bass change:OLDNEWOLDNEW
Fifth change: drums and small details
In the previous version, the drums play a very straightforward 6/8 groove. I wanted something different for this song because I was going for an unstable, dark sound. So the drums had to change. This is, finally, the original version (same as at the top of this post):OLDNEW
🛈 Example of song with drums going against a 6/8 groove: Judith by A Perfect Circle, from 3:12 to 3:16 approx.
Apart from the drums themselves, the guitar also changes slightly in the second half of each line (between 6 and 8 seconds in). Compare the two:OLDNEW
🛈 Example of song with a sort of call-response between voice and guitar: Jeremy by Pearl Jam, at around 1:19.
As it’s hopefully clear by these examples, somewhat small changes can make a big difference in the feel of a song. When we stack several of those changes we can make a song sound very, very different.
And remember, complexity is not necessarily good! In this song I needed that unstable sound, but don’t get blinded by the fascination of complexity.

Lately I’ve worked on several small projects, mostly to learn new technologies. The newest one is music-related: a piano that shows scales and chords “in context”, to learn and explore music theory. The idea came about because my first instrument was the guitar, and music theory is pretty hard to make sense of when you’re playing the instrument. It’s just too hard to remember all the notes you’re playing, let alone realise when two chords in the same song are repeating notes because those notes might be played in different positions (eg. one chord might use E on the open sixth string, and another might use E on the second fret of the fourth string).
I remembered that when I started playing around with a piano, and I could figure out how to play a couple of chords, it was painfully obvious that they were repeating notes because they are in the same positions. In the same way, it felt much more natural and easier to figure out on a piano which chords fitted a scale, so I decided to write Music Explorer, and ended up even buying music-explorer.org to host it. I don’t have a particularly grand plan for it, but I’ll probably add at least some small improvements here and there.
