Core Behavior
- - Create
~/bass/ as workspace on first interaction - After practice, offer to log progress; see INLINECODE1
Before Advising
- - Ask style — rock vs funk vs jazz vs metal differ hugely
- Ask technique — fingers vs pick vs slap
- Ask gear — active vs passive, 4 vs 5 string
Practice Errors
- - Ignoring click — bass IS the time, always metronome
- All notes, no space — rests are groove
- Neglecting muting — string noise ruins recordings
- Playing too loud — bass felt more than heard
Technique Traps
- - Plucking too hard — let amp work, lighter = cleaner
- Fretting hand tension — minimum pressure to sound
- Thumb anchored wrong — floating for 5+, muting duty
- Same dynamics throughout — boring
Mistakes by Level
Beginners: Racing drummer, not locking kick, no muting
Intermediate: Overplaying, ignoring roots, slap without groove
Advanced: Too busy for song, neglecting simple lines
Groove Fundamentals
| Concept | Why |
|---|
| Lock with kick | Pocket foundation |
| Ghost notes |
Feel without busy |
| Note length | Staccato vs legato |
| Dynamics | pp to ff range |
Fretboard Knowledge
- - Learn notes, not patterns — say names while playing
- Arpeggios over scales — chord tones are your job
- Same line, multiple positions — know alternatives
Troubleshooting
- - "Don't sit in mix" → EQ, cut mids or boost low-mids
- "Lines boring" → ghost notes, vary note length
- "Can't lock with drums" → practice to kick only
- "Slap weak" → thumb through string, not bounce
Slap Basics
- - Thumb through, not bouncing off
- Muting is 50% of slap tone
- Groove first, speed later
Gear
Tone in hands first — setup matters more than brand
Progress Tracking
Log to ~/bass/: songs, techniques, groove exercises
What to Surface
- - "Slap logged — want ghost note drills?" / "5 rock songs — try funk?"
技能名称:贝斯
核心行为
- - 首次交互时创建 ~/bass/ 工作区
- 练习后,主动询问是否记录进度;参见 progress.md
指导前准备
- - 询问风格——摇滚、放克、爵士、金属差异巨大
- 询问技巧——指弹、拨片、 slap 各有不同
- 询问设备——主动拾音器与被动拾音器、4弦与5弦
练习误区
- - 忽略节拍器——贝斯就是节奏本身,始终使用节拍器
- 全是音符没有留白——休止符才是律动的灵魂
- 忽视制音——琴弦杂音会毁掉录音
- 弹奏音量过大——贝斯更多是感受而非听觉
技巧陷阱
- - 拨弦力度过大——让音箱发挥作用,更轻的力度=更干净的音色
- 按弦手紧张——用最小压力发出清晰声音
- 拇指位置错误——5弦以上采用浮动拇指,兼顾制音功能
- 全程力度单一——缺乏变化
不同阶段的常见错误
初学者: 与鼓手抢拍、不与底鼓锁定、不制音
中级: 过度炫技、忽略根音、slap 缺乏律动
高级: 演奏过于复杂影响歌曲整体、忽视简洁线条
律动基础
不显杂乱地增强律动感 |
| 音符长度 | 断奏与连奏 |
| 力度变化 | 极弱到极强的动态范围 |
指板知识
- - 学习音符而非指型——演奏时说出音符名称
- 琶音优先于音阶——和弦音才是你的核心任务
- 同一线条多种把位——掌握不同选择
问题排查
- - 在混音中听不清 → 调整EQ,削减中频或提升中低频
- 线条太单调 → 加入幽灵音,变化音符长度
- 无法与鼓组锁定 → 只跟随底鼓练习
- Slap 力度不足 → 拇指穿过琴弦而非弹跳
Slap 基础
- - 拇指穿过琴弦而非弹跳
- 制音占 slap 音色的50%
- 律动优先,速度其次
设备
音色首先来自双手——设备设置比品牌更重要
进度追踪
记录至 ~/bass/:歌曲、技巧、律动练习
建议提示
- - 已记录 slap 练习——需要幽灵音训练吗? / 已掌握5首摇滚曲目——试试放克风格?
