A lo-fi piano is the soft, dusty, slightly wobbly piano you hear all over lo-fi hip hop and chillhop. It is an ordinary piano with a particular set of treatments over it, played in a particular way. Here is what makes it and how to get there.
Works in any DAW, with any piano sound. Nothing here needs a particular plugin.
A lo-fi piano is a soft, close, slightly out of tune piano with a gentle tape wobble, a bed of vinyl crackle underneath, and the bright top rolled off, played quietly with loose timing. It is not a special instrument. It is a normal piano source plus a stack of small treatments plus a way of playing that leaves the edges rough.
So it starts from a piano you already have. A felt piano or a soft piano patch gets you most of the way, because it is already muted and close. A sampled upright works. Honestly any piano patch works, as long as you keep it mellow and close rather than the big, bright, concert grand sound. The lo-fi part comes from what you do to it and how you play it, not from the piano itself.
The ingredients are consistent from track to track:
The character is what earns the name, but the piano and the playing are what make it music. Get a nice mellow piano and a good loose take first, then age it.
You stack a set of small treatments over a soft piano source: tape wow and flutter, vinyl crackle, a low-pass filter, saturation, a touch of detune, and a little room. The trick is that each one stays gentle and they work together, rather than any single effect turned up loud.
| Treatment | What it does | Keep it |
|---|---|---|
| Soft source | A felt or soft piano, mellow and close | Start here, not on a bright grand |
| Wow and flutter | Slow and fast pitch wobble from tape | Gentle, most obvious on held notes |
| Vinyl crackle | A bed of surface noise and hiss | Low, felt more than heard |
| Low-pass filter | Rolls the bright top off | Soft, stopping short of muffled |
| Saturation | Tape warmth, rounds and thickens | Barely audible as an effect |
| Detune | A few cents out of tune | A touch, not seasick |
| Room or reverb | A short room or small plate | Small, just to place it in a space |
Taking each in turn. Wow and flutter is the drifting, slightly seasick pitch wobble of tape running at an uneven speed, and it is the single treatment that most says lo-fi. Keep it low, because a piano has clear pitch and the ear notices wobble on it fast. How far to push it, and the numbers a real deck actually hits, are written up in the tape sound guide.
Vinyl crackle is a constant bed of surface noise under the piano. Keep it low so it sits in the gaps between the chords. If you can hear it as a separate element, it is too loud. The low-pass filter takes the sparkle off the top so the piano sounds like it was recorded onto something old, and this alone is most of the effect. Roll off the highs until it sounds soft, then stop before it sounds muffled.
Saturation adds tape or tube warmth and rounds the attack of each note. It is right when it is barely audible as an effect and you only notice it when you bypass it and the piano goes thin and spiky. A touch of detune and a little pitch drift stop the piano sounding like a locked digital sample. And a short room or small plate reverb places the piano in a space, so it feels like a mic in a room rather than a dry patch.
The wear sits under the piano, it does not replace it. It is tempting to reach for crackle and wow first because they are the fun part, but they only flatter a piano that already sounds good and is played well. Get the mellow piano and the loose take right, then age it.
Play it softly, loosely and simply. A light touch, timing that sits slightly off the grid, and small mistakes left in rather than quantized out. The playing does as much for the sound as any of the treatments, and no amount of crackle rescues a stiff, hard, perfectly gridded take.
A lo-fi piano is quiet and intimate, so keep the touch light and the velocities low. Playing hard brings the bright hammer sound back and undoes the softness you were after. If your source gets brighter the harder you hit it, and most piano sounds do, then staying soft is doing part of the filtering for you.
Let chords land a little early or late instead of quantizing them hard to the grid. That small drift is a large part of why the good ones sound relaxed and human rather than programmed. The swing and behind-the-beat feel that the rest of the track sits in are covered in the lo-fi beat guide.
A note that is slightly fluffed, a chord where the notes do not all land at once, a bit of pedal or key noise. These are the things that make it sound like a person at a piano rather than a grid, and clearing them all out is usually a step backward. Keep it sparse too, a few chords with space between them, and let it breathe.
Jazzy extended chords, mostly sevenths and ninths rather than plain triads. Major 7ths, minor 7ths and dominant 9ths do most of the work. The soft, wistful, slightly unresolved quality that the style lives on comes almost entirely from those extensions.
A plain triad sounds clean and poppy. Add the 7th, and then the 9th, and the same three root notes turn reflective and a little unresolved, which is the sound you are chasing. If the seventh chord is new to you, the seventh chord guide explains what it is and how it is built.
Two things about voicing them. Keep the notes close together in the middle of the keyboard rather than spread wide, which is warmer and less showy. And move as little as possible between chords, keeping common notes where they are and shifting only what has to shift. Keep the progression short, two or four bars, and let it loop, because in this style the loop is the point.
Most of this is quick to set up over a piano you already have. The part that is genuinely hard to fake by hand is the aged, drifting quality that keeps moving so the piano never sounds like the same bars pasted end to end.
SILT is a generative tape-loop instrument. Play a piano into it, or drop a piano sample in, and it smears the sound with tape wow, flutter, dust and dropout until it becomes exactly the soft, dusty, wobbly lo-fi piano this whole guide is about. It runs in the browser, or as an Audio Unit, a VST3, an AAX and a standalone.
It is a tape instrument, not a piano, so it does not replace your piano sound. Bring your own piano source or play one in, or use the loop material it ships with, which is cleared for you to use in your own tracks. What SILT adds is the tape character, the wear and the movement over the top.
Free to hear in the browser, no signup. Everything above still works by hand in any DAW, which is rather the point of writing it down.
