Definition and role
The lead is the synth that brings the main melody (or the instrumental riff/hook) to the foreground. It must be recognizable, intelligible at any volume, and capable of expression: glide, vibrato, dynamics.
Characteristics of a good lead
- Defined attack (attack 0–10 ms) to articulate the notes.
- Clear presence zone: the lead lives between 1 and 5 kHz; it should leave 200–500 Hz to everything else.
- Expression: glide (portamento) 20–80 ms in legato mode, delayed vibrato (LFO 5–6.5 Hz, ±10–30 cents, kicking in after 200–400 ms), velocity on the filter.
- Monophonic or poly depending on the melody: mono legato for solos and synthetic toplines, poly for chord hooks.
Lead families
| Type | Source | Genres | Notes |
|---|---|---|---|
| Classic saw lead | 1–2 saws, 24 dB LP | synthpop, prog, synthwave | Minimoog-style |
| Square / pulse | square or PWM | chiptune, synthwave | “hollow”, tied to 8-bit video games |
| Sync lead | hard sync | rock, new wave, EDM | aggressive |
| Supersaw lead | 7+ voices | trance, EDM, future bass | wide, needs space |
| FM lead | operators, 1:1/1:2 ratio | city pop, fusion | bell-like |
| Distorted lead | saw/square + overdrive | hard techno, hyperpop | huge presence |
| “Vocal” lead | formants, vocal wavetables | pop, hyperpop | sounds like it is singing |
| Whistle / sine | sine + vibrato | G-funk | The “whistling” G-funk lead, often from a Minimoog or similar synths |
Basic recipe (mono subtractive lead)
Osc 1 saw, osc 2 saw +7 cents, osc 3 square an octave below at −12 dB. 24 dB LP at 3 kHz, resonance 20%, tracking 70%, filter envelope amount +30% decay 300 ms. Amplitude A 2 ms, D 200 ms, S 80%, R 150 ms. Glide 50 ms legato. Vibrato: LFO 5.8 Hz on pitch, ±15 cents, assigned to the mod wheel. Light saturation, ping-pong dotted eighth-note delay 20% wet, 1.2 s plate reverb.
Lead mix
- EQ: HP at 150–250 Hz (depends on the register), 2–3 dB reduction at 300–500 Hz, presence at 2–4 kHz, a possible cut at 6–8 kHz if it whistles.
- Conflict with the vocal: lead and vocal should not play together in the same register; if it happens, put the lead an octave above or below, or use a dynamic EQ on the lead driven by the vocal.
- Light compression for evenness (2–4 dB).
- Stereo: a mono, centered lead is stronger; give width with delay and reverb, not by widening the dry signal.
- Automation: cutoff and delay send on the final notes of phrases (throws).
Example in A minor
Instrumental hook of a synthwave track at 104 BPM over Am – F – G – Em: melody E5 – D5 – C5 – B4 – A4 in eighth notes with legato and 40 ms glide on the passing notes, vibrato with the mod wheel only on the long notes. Lead in Mini V (3 oscillators, ladder filter), doubled an octave above by a pulse wave at −14 dB for brightness.
Listening references
The Minimoog leads of '70s prog; the G-funk of Dr. Dre and Warren G (“whistling” sine leads with portamento); the supersaw leads of trance; the distorted leads of hyperpop.
Common mistakes
- Lead too wide and with too much reverb: it loses presence.
- Glide always on: staccato notes become “slippery”.
- No expression: it sounds like flat MIDI. Record the mod wheel and pitch bend.
Exercise
- Create 4 leads (saw, square, sync, FM) and play the same melody; choose the one that holds up best in the mix with the vocal.
- Record a melody with “played” glide and vibrato (mod wheel) and one without: compare.
