Definition
A fill is a figure that interrupts the groove to signal the end of a phrase and the arrival of the next section. A transition is broader: the set of gestures (fills, risers, stops, arrangement changes) that connects two sections. They work like the punctuation of a text: commas (one-beat fill every 4 bars), periods (one-bar fill at the end of a section), line breaks (break, drop).
Lengths and positions
- One-beat fill (the last beat of a 4- or 8-bar phrase): keeps the flow, typical of pop and rock.
- Two-beat or one-bar fill: end of verse → chorus.
- Fill of two bars or more: end of bridge, last chorus, solo.
- Pickup: a fill that starts before the bar it belongs to and crosses the barline (anacrusis).
- The fill ends on 1 of the new section, with crash + kick: that is the arrival point, not the fill.
Types
- Descending tom fill (high → low): the rock classic, sixteenth notes or triplets.
- Snare roll in crescendo: marching, EDM build-up.
- Fill by subtraction: remove the kick or hi-hat for half a bar or a bar; the emptiness creates anticipation (widely used in modern pop and trap).
- Stop / break: the whole band stops on one hit (often on the “&” of 4) and restarts on 1.
- Hi-hat fill (trap): rolls in triplets or thirty-second notes, pitch changes in the roll.
- Bass or harmony fill: chromatic walk-up to the root of the new chord (G – G# – A toward Am).
- Tihāi (from Indian music): a phrase repeated three times that lands exactly on 1.
Transitions in electronic music
- Build-up of 8 or 16 bars: the roll doubles its subdivision every 2–4 bars (quarters → eighths → sixteenths → thirty-seconds), the high-pass filter rises on music and drums (from 20 Hz to 300–800 Hz), noise risers, rising pitch.
- Drop-out: silence or only vocal/FX for the last beat or the last bar before the drop; it increases the impact by contrast.
- Reverse cymbal / reverse reverb: a reversed sound that culminates exactly on 1.
- Impact and sub drop on the 1 of the drop.
- Downlifter (descending noise) to exit a drop into a break.
Practical rules
- Increasing density: the fill should become denser or louder toward the end.
- Register: going from highest to lowest brings energy “downward,” toward 1.
- Consistency: use the same family of fills throughout the song, intensifying it at the end.
- Room for the vocal: no fills over the last word of an important vocal phrase, or move the fill.
- Chords: a fill that anticipates the new chord by an eighth note (push) makes the transition smooth.
Example in A minor (pop at 100 BPM)
End of pre-chorus on G (VII): drums drop the kick in bar 7, in bar 8 the snare plays sixteenth notes in crescendo from beat 3, bass G – G# – (rest on the “&” of 4), sustained vocal. Chorus on 1: Am with crash, kick and sub re-entering. The bass's G# is the leading tone of A: the chromatic walk-up makes the resolution inevitable.
In FL Studio
- Create dedicated patterns (“Fill 1,” “Fill 2”) instead of modifying the main loop.
- Use the “Chop” function or the Riff Machine to generate variations, then clean up.
- Filter automation (Fruity Filter or Parametric EQ 2) on the music bus in the build; volume automation for the drop-out.
- For risers: white noise in a synth (3x Osc, Sytrus) with an automated band-pass, or dedicated FX (e.g. Fruity Granulizer on a crash).
Exercise
- Take an 8-bar loop and create four versions of the last bar: tom fill, roll, fill by subtraction, stop. Judge which one best prepares the chorus.
- Build a 16-bar build-up with the roll doubling every 4 bars and a high-pass filter from 30 to 600 Hz, then a one-beat drop-out.
- Write a tihāi that ends on the 1 of the drop.
