Making frequency music requires a digital audio workstation (DAW), a signal generator plugin, and a basic understanding of which frequencies produce which effects. Whether you’re creating solfeggio tones, binaural beats, or isochronic pulses, the core process involves generating precise sine waves and layering them with intention. Here’s how to do it from scratch.
Choose Your DAW and Signal Generator
Most major DAWs come with a built-in tool for generating pure tones. In Pro Tools it’s called Signal Generator, Logic Pro has Test Oscillator, and Cubase includes TestGenerator. These plugins let you dial in a specific frequency in hertz and output a clean sine wave. If your DAW doesn’t have one, free options like Audacity work well for basic tone generation, and free VST plugins can fill the gap in more advanced setups.
You don’t need expensive gear to start. A computer, headphones for monitoring, and your DAW are enough. If you plan to publish your tracks, a decent audio interface helps keep the output clean, but it’s not essential for learning the process.
Why Sine Waves Matter
Frequency music almost always uses sine waves rather than square, triangle, or sawtooth waves. The reason is simple: a sine wave contains only its fundamental frequency with no harmonic overtones. A square wave, by contrast, produces strong odd harmonics at three times, five times, and seven times the base frequency. Those extra frequencies muddy the tone and interfere with the precise effect you’re trying to create. If you want a pure 528 Hz tone, a sine wave gives you 528 Hz and nothing else. A square wave gives you 528 Hz plus unwanted energy at 1,584 Hz, 2,640 Hz, and beyond.
Solfeggio Frequencies and What They Target
Solfeggio frequencies are a set of specific tones ranging from 174 Hz to 963 Hz, each associated with different physical or psychological effects. To create solfeggio music, you generate a sine wave at the exact target frequency and then layer it with ambient textures, pads, or nature sounds to make it listenable over longer periods.
The nine core solfeggio frequencies are:
- 174 Hz: Associated with pain and stress relief, muscle relaxation, and physical healing. Often described as the frequency with the greatest potential effect on the body.
- 285 Hz: Linked to tissue repair, immune support, and feelings of safety.
- 396 Hz: Aimed at releasing guilt, fear, and grief.
- 417 Hz: Associated with facilitating change and clearing negative energy.
- 528 Hz: Considered especially effective for sleep quality and stress reduction. One of the most popular solfeggio tones.
- 639 Hz: Connected to relationships and emotional balance.
- 741 Hz: Called a “detoxifying frequency,” sometimes used by people dealing with chronic pain.
- 852 Hz: Aimed at replacing negative thoughts with positive ones, potentially helpful for anxiety.
- 963 Hz: Associated with mental clarity, intuition, and heightened awareness.
To produce a solfeggio track, open your signal generator, set it to the desired hertz value, and render a sine wave at that frequency for the length of your track. Then build around it. Many creators add reverb to soften the tone, layer in gentle piano or synthesizer pads tuned to complementary notes, and mix in recordings of rain, ocean waves, or forest sounds. The sine wave acts as the backbone while the ambient layers make the track something people can listen to for 30 or 60 minutes.
How to Create Binaural Beats
Binaural beats work differently from single-frequency tones. You send one frequency to the left ear and a slightly different frequency to the right ear. The brain perceives a third tone equal to the difference between the two. For example, playing 400 Hz in the left ear and 410 Hz in the right ear causes the brain to perceive a 10 Hz pulse, which falls in the alpha brainwave range associated with relaxation.
The key decision is choosing your target brainwave frequency, then building your two carrier tones around it. Here are the standard brainwave bands:
- Delta (below 4 Hz): Deep sleep. Use a difference of 1 to 4 Hz between your two tones.
- Theta (4 to 8 Hz): Meditation, drowsiness. A 6 Hz difference, for example, means setting one channel to 200 Hz and the other to 206 Hz.
- Alpha (8 to 13 Hz): Calm focus, relaxation. A 10 Hz difference is a common starting point.
- Beta (13 to 30 Hz): Active thinking, concentration.
- Gamma (above 30 Hz): High-level processing, problem-solving.
In your DAW, create two separate audio tracks. On each, place a signal generator set to your chosen carrier frequencies. Pan one track fully left and the other fully right. This hard panning is essential because binaural beats only work when each ear receives a different frequency. Research suggests that lower carrier tones (in the 100 to 500 Hz range) tend to produce more noticeable effects than higher ones. Render both tracks together as a stereo file, and your binaural beat is complete.
A 2025 systematic review found that binaural beat interventions produced moderate improvements in anxiety, sleep quality, and cognitive performance in young adults, with effect sizes in the 0.3 to 0.6 range. That’s a meaningful but not dramatic effect, roughly comparable to other relaxation techniques.
How to Create Isochronic Tones
Isochronic tones take a different approach. Instead of relying on two frequencies and the brain’s interpretation, they use a single tone that pulses on and off at a steady rhythm. A 10 Hz isochronic tone is a sine wave that gets louder and softer 10 times per second. The rhythmic pulsing is what drives the brainwave entrainment effect, and unlike binaural beats, isochronic tones work through speakers without headphones.
The simplest way to make them is with Audacity and a free plugin called Isomod, which automates the volume pulsing for you. In a full DAW, you can achieve the same result by applying a low-frequency oscillator (LFO) to the volume of a sine wave track. Set the LFO rate to your target brainwave frequency. For a theta-range isochronic tone, set the LFO to pulse at 6 Hz. The tone should go from full volume to silence and back in each cycle, creating a sharp, distinct pulse rather than a gentle wobble.
Many producers calibrate the volume of their isochronic tones to follow the dynamics of background music, so the pulses blend naturally rather than sounding mechanical.
Working With 432 Hz Tuning
Some frequency music creators tune their entire project to 432 Hz instead of the standard 440 Hz concert pitch. Advocates claim this tuning feels more natural and calming. To make the switch, you need to detune every instrument and sample in your project down by 32 cents (the precise value is 31.77 cents). Most DAWs and software synthesizers have a master tuning or fine-tune knob that lets you make this adjustment. In some DAWs, you can set this globally so every virtual instrument follows the new tuning automatically.
If you’re working with pre-recorded audio rather than virtual instruments, you can pitch-shift the entire file down by 32 cents using a pitch correction tool. Just be aware that pitch-shifting audio can introduce subtle artifacts, especially on percussive or vocal material.
Mixing Multiple Frequency Layers
When you start combining sine waves, ambient textures, and background music, phase cancellation becomes a real concern. Two sine waves at similar frequencies can partially or fully cancel each other out when their waveforms collide, leaving you with silence or a thin, hollow sound where a full tone should be.
To avoid this, keep each frequency element at a balanced level so no single tone dominates the mix. Use panning to give each element its own space in the stereo field. If you’re layering a 528 Hz solfeggio tone under ambient pads, make sure the pads don’t have strong harmonic content right at 528 Hz, or the two will fight. A simple spectrum analyzer plugin can show you where energy is piling up.
Keep the overall volume moderate. Research on auditory stimulation safety recommends staying below 85 decibels to avoid hearing damage over time, and frequency music is typically listened to for extended sessions of 30 minutes or more, which makes safe volume levels especially important. People with epilepsy should check with their doctor before using binaural beats or isochronic tones, as rhythmic auditory stimulation can be a trigger.
Putting a Full Track Together
A typical frequency music track follows a simple structure. Start with your core frequency element: a solfeggio sine wave, a binaural beat pair, or an isochronic pulse. Layer ambient sounds underneath, keeping them soft enough that the frequency tone remains present but not so loud that the track feels clinical. Add a slow fade-in over the first 30 to 60 seconds and a gradual fade-out at the end.
Most frequency music tracks run between 15 and 60 minutes because the entrainment effect takes time to develop. A three-minute track won’t give the brain enough exposure to settle into a new brainwave pattern. When exporting, use a lossless format like WAV or FLAC. Compressed formats like MP3 can alter the precise frequency content of your tones, which matters more here than in conventional music production. If you’re creating binaural beats specifically, always export in stereo to preserve the left/right channel separation that makes them work.
