如何製作 Lo-Fi 吉他和弦

Lo-Fi 吉他和絃應是什麼聲音

Lo-fi 吉他不追求完美演奏，而追求有磨損感的質地：稍微偏軟的音準、鈍一點的瞬態、像舊音箱一樣的噪聲底。

從中間弦上的三和絃、maj7、min7、min9 或 add9 開始，避免開放低 E 讓小音箱上的低頻變渾。

Lo-fi hip-hop 裡的節奏吉他常在第二拍和第四拍做短促 stabs；太長的 sustain 會和稀疏鼓組搶空間。

如果沒有實錄吉他，可以用 nylon 或 clean electric 取樣，再用 amp sim、低通和輕飽和做出房間感。

Detune a duplicate layer by five to fifteen cents left and right for chorus width without full double tracking.

Low-pass around 6–9 kHz tames harsh pick attack; combine with gentle tape saturation instead of bright EQ boosts.

Room reverb under 1.2 seconds and pre-delay under 20 ms keeps chords intimate.

Sidechain chord bus lightly to kick so low mids pump subtly in trap-influenced lo-fi.

Humanize velocity and start times ±10–20 ms in your DAW piano roll or midi strum tool.

Baroque or jazz voicing extensions (maj7, min9) sound more 'sampled vinyl' than power chords.

Print chord loop to audio once tone is set, then chop in the playlist for boom-bap style repeats.

Noise layer: vinyl crackle at -40 dBFS under chords glues the stack—print or send to a bus.

Mono fold check: wide detuned guitars can lose center energy; keep bass notes mono below 120 Hz.

Acoustic piezo DI benefits from boxiness cut at 300 Hz before lo-fi low-pass.

Electric with single-coil picks up hum—gate gently or embrace hum for authenticity.

Capo changes timbre; capo 4 on acoustic reads 'bedroom' on many lo-fi playlists.

Lo-fi guitar is less about perfect takes and more about worn texture: slightly flat chords, soft transients, and noise floor that feels like a thrift-store amp.

Start with simple triads or seventh chords voiced on middle strings to avoid muddy low E on small speakers.

Rhythm guitar in lo-fi hip-hop often stabs on beat two and four with short decay—long sustain fights sparse drums.

Use nylon or clean electric samples when you do not record live; amp sim afterward sells the space.

聲部、調性和節奏

把主和絃寫在 C2–C4 附近，讓 bass、808 和人聲有足夠空間。頂聲部的小幅調整常比再加一條 lead 更自然。

在人聲友好的 beat 裡，和絃可以有顏色，但不要把每個小節都塞滿延伸音。保留空拍，讓 artist 能寫 hook。

在 MIDI strum 工具或 piano roll 中把起始點和力度輕微隨機化，通常 ±10–20 ms 就足夠。

Midi strum patterns vary per bar slightly so loops do not hypnotize negatively.

Key choice: flat keys (Eb, Ab) match many soul samples; match sample key when flipping.

Chord inversions on top voice movement create melody without separate lead line.

Avoid massive stereo widener on low chord bodies—widening above 2 kHz only is safer.

Plugg Supply amp sims and cassette emulations install via verified Telegram delivery—compare one clean and one broken amp model.

808 and chords: high-pass chords at 100–120 Hz; let 808 own sub.

跑調、濾波和飽和

複製一層和絃，左右各偏移 5–15 cents，可以得到 chorus 寬度而不必完整 double tracking；超過這個範圍容易聽起來暈。

在 6–9 kHz 附近低通可壓住撥弦的刺耳感。與其提升高頻，不如用 tape saturation 或 cassette emulation 增加溫暖。

房間混響控制在 1.2 秒以內，pre-delay 低於 20 ms，能讓和絃保持親近而非漂到背景裡。

可在 -40 dBFS 左右鋪一層 vinyl crackle，但要高通，避免削弱底鼓瞬態。

Vocal space: dip chords 2–4 kHz when vocals enter or automate chord bus level.

Spring reverb on guitar only on bridge sections for contrast with dry verses.

Fingerpick patterns softer than pick for study-beats aesthetic.

Downsample or bit-crush send parallel at 10% blend for digital lo-fi edge.

一步步搭建吉他和絃層

FL Studio 與 Ableton 的 Lo-Fi 吉他流程

在 FL Studio 中，把吉他放到獨立 mixer track，先調 amp sim，再用 Parametric EQ 做高通/低通，最後把 pitch、chorus 或 tape send 自動化。

在 Ableton 中，可用 Audio Effect Rack 做一個宏：Filter、Saturator、Chorus 和短 Reverb 一起控制，方便每個段落微調灰塵感。

Plugg Supply 上的 amp sim、cassette emulation 和 reverb 會在收錄前驗證檔案，透過 Telegram 獲取時仍要按自己的系統路徑安裝並重新掃描外掛。

Export loop one bar longer for crossfade in sampler instruments.

Reference Khruangbin, Mac Demarco guitar density—not loudness, but space and mid focus.

Live take one pass with metronome off for drift; quantize to 70% strength.

Use tape stop effect on last chord of phrase sparingly for arrangement punctuation.

層級 Rhodes under guitar at -8 dB for harmonic fill when guitar voicing is thin.

Guitar amp sim input from line-level IR avoids unrealistic drive on direct input.

Check chord loops in mono Bluetooth speaker test for midrange masking.

Save pedalboard order: compressor before amp, modulation before delay, reverb last on insert.

讓和絃、鼓和 808 共存

和絃匯流排通常在 100–120 Hz 以下高通，讓 808 佔據 sub。若底鼓一進來中低頻擁擠，可輕微 sidechain 1–2 dB。

做人聲 beat 時，在 2–4 kHz 給主唱留通道。可以動態 EQ 或自動降低和絃匯流排，而非把吉他整體做得過暗。

寬聲像吉他要做 mono fold 檢查。低頻主體保持居中，只把上方泛音、delay 或 detune 層做寬。

Plugg Supply 上可用的吉他質感工具

優先找三類工具：幹淨或破舊的 amp sim、輕量 tape saturation、適合短房間感的 reverb。不要在一個 loop 上堆太多同類外掛。

建立一個模板：DI/取樣吉他、amp sim、EQ、saturation、短 reverb send、vinyl noise send。聲音確定後匯出成 audio，方便後續切片。

下載免費外掛和素材時避開 repack 網站；使用已驗證來源可降低損壞檔案、廣告安裝器和授權不清的問題。

常見 Lo-Fi 吉他錯誤

錯誤一：把所有層都做寬，成果 mono 下中心能量消失。低音和主和絃身體應更穩定。

錯誤二：用過長混響遮住不穩的演奏。Lo-fi 可以粗糙，但 groove 和節奏位置仍要可信。

錯誤三：低通太狠導致和絃沒有存在感。先控制刺耳點，再保留足夠中高頻讓吉他能被聽見。

錯誤四：在人聲開始後不讓位。Lo-fi 仍需要明確的主次關系。
