![]() For the chords themselves, choosing the chords for the progression can take some experimenting, listening to what sounds good together, etc. To make things simple, let’s stick to the A minor scale created earlier. After creating the chord progression, you’ll get a general feel for the track you're trying to make and perhaps add a melody on top.įirst, pick a scale. Once you have the BPM, you’re ready to build a chord progression. Create main chords and chord progressions. To set the BPM, use the Transport object you used earlier like so: = 150 2. Melodic dubstep is typically around 140-150 BPM. BPM is short for beats per minute, and it's a basic indicator for the tempo of the track. To start, decide what the BPM for the track is going to be. For me, I’m choosing electronic music, something with a melodic dubstep feeling. So, let’s try making a part of a song with the knowledge you’ve gained and the functions you’ve implemented above. Having gone over the setup and how to create scales and chords, you're now ready to create a song! Producing a full song takes a long time. However, for simplicity’s sake, let’s leave the function as is here. You could expand here if you like with error handling if you provide a note which doesn't exist in the provided scale, or perhaps an incorrectly formed scale. Now you know how to get the notes to take the third and fifth notes and return the chord as an Array. To counter this issue, simply go back to the start of the scale and then up an octave (i.e., add 1 to the octave number), thus preserving the chord. However, the issue here is that you’re also dealing with octaves, so the next note in the scale may be out of bounds. Normally you’d just add 2 or 4 to the root note index and get the next chord notes no problem. Let's reuse the function you created beforehand. Okay, so first, you need to get the scale with the octave numbers. const synth = new Tone.Synth().toMaster()ĭocument.getElementById("play-button").addEventListener("click", function() ` Ĭonst thirdNote = getNextChordNote(rootNote, 3)Ĭonst fifthNote = getNextChordNote(rootNote, 5)Ĭonst chord = I'll show you what it does in just a bit. ![]() For now, just add the following code to the music.js file. Let's demo the button element later on to trigger sound, and start with the music.js the file.įirst, let's make a little "hello world" type app to see if the framework works. The first line imports the Tone.js framework from the web. For the sake of simplicity and concentrating on the framework, here’s how you can create a single HTML file with the following content: There are a couple of ways to set up the project framework, such as using npm or node package manager. Consider this a guide, we’re in this journey together, you and me. In this blog, I’ll go over the basics of how to make music using Tone.js and JavaScript. That being said, it also allows for heavy customization in many ways (which I’ll get into later on in the article). It's fairly robust and simple to use, which is great for beginners learning to program and produce music. It's built on top of the Web Audio API as an abstraction layer, which makes for a perfect tool to create music using JavaScript. Tone.js is a nice, extensive framework aimed to create music and play it in a web browser. I immediately thought to myself, "Okay, programming could really come in handy here." Most of my background was in web development, so I looked around for something JavaScript-based that I could use. As I started learning more about music production and theory, I started seeing patterns in many places, such as how scales were created, how the most basic chords were made, etc. Making music with Tone.js and JavaScriptĬreating music has a lot more in common with programming than one might think. I began thinking about how to split my time pursuing these two passions. Like coding, I started studying producing music in-depth. Recently, I found that another activity creeping its way onto my passion list-music production. I can, without a doubt, say that coding is a passion of mine as it is to so many of my peers. As programmers, we’re constantly learning new technologies and new principles, adapting as we go, and never stopping. And yet programming is so much more than that. You like the feeling you get when you solve a complex problem when you optimize a system or perhaps even solve that pesky little error that's been bugging you for the entire week. If you're anything like me, you love coding.
