  "title": "钝感练习",
  "lyrics": "[intro]\n(Hook-DNA: Rhythmic pattern is steady 16th notes; pitch anchor circles the root and 5th; a 2-bar pattern repeats with slight melodic variation.)\n(Mix: Wide stereo field from pads/FX, centered low-end kick/bass. Clean high-end. Heavy sidechain compression on synths ducking to kick. Large hall reverb on synths, plate reverb on clap.)\n(Inst: Filtered supersaw synth pads, plucky synth arpeggio, driving four-on-the-floor kick drum.)\n(Chords: G#m - E - B - F#)\n\n[verse]\n(Melody-Contour: Narrow range, stepwise motion; phrases land on stable chord tones; conversational, on-the-beat rhythm.)\n(Inst: Kick and clap pattern continue, sub-bass plays root notes. A soft, bell-like synth melody enters. Main synth pads are filtered down.)\n(Vocal-Perf: Soft, breathy chest voice, mezzo-piano.)\n(Chords: G#m - E - B - F#)\n体检报告压在包里没拆封\n医生说过度紧绷迟早要出错\n我给焦虑标了价 按小时计算\n发现比正常人多出整整一倍的账\n(Transition: White noise riser begins to swell.)\n\n[pre-chorus]\n(Melody-Contour: Ascending line, building tension; notes lengthen and rise in pitch; urgent, driving rhythm.)\n(Inst: Snare roll builds intensity. Supersaw pads open filter, becoming brighter and louder.)\n(Vocal-Perf: Volume increases to mezzo-forte, more projected tone.)\n(Chords: C#m - G#m - E - F#)\n练习对所有事情不在意\n练习把锐角磨成圆弧形\n练到后来真的有点成功了\n偏偏在你面前 那套全部失灵\n(Transition: All instruments cut for one beat, leaving only vocal reverb tail.)\n\n[chorus]\n(Hook-Recall: The anthemic vocal melody soars over the full instrumental, while the plucky synth arpeggio from the intro returns.)\n(Melody-Harmonic-Tension: Melody peaks on the high root over the tonic chord, creating a powerful, stable arrival point. Phrases often end on the 5th over the mediant chord, creating momentary suspension.)\n(Melody-Contour: Wide leaps, long soaring notes; peaks on downbeats of key phrases; powerful, sustained rhythm.)\n(Inst: Full instrumental force. Heavy kick, bright supersaw pads, driving plucky synth arpeggio.)\n(Vocal-Perf: Full power, forte dynamic, controlled vibrato on sustained notes.)\n(Chords: G#m - E - B - F#)\n你是我钝感练习里 唯一的漏洞\n越想不在乎 越在乎得清醒\n所有的无所谓 碰到你就穿帮\n原来我根本 没练成过\n(Transition: A synth swell and reverse cymbal effect create a wash into the bridge.)\n\n[bridge]\n(Melody-Harmonic-Tension: Melody holds a dissonant 4th over the tonic chord, creating sharp tension before resolving down. The section ends on the V chord, leaving harmonic tension unresolved leading into the final chorus.)\n(Melody-Contour: Starts low and reflective, builds in a long ascending arch to an emotional peak; rhythm is more legato and free.)\n(Inst: Beat drops to a half-time feel, then returns with a building snare roll. Reverb-drenched piano arpeggios replace the main synth.)\n(Vocal-Perf: Builds from intimate and soft to maximum emotional intensity.)\n(Chords: C#m - G#m - E - B - C#m - E - F# - F#)\n你说喜欢我皱眉头的样子\n我才发现我在你面前从没忍过\n那些在别人面前咽下去的委屈\n到你这里全变成了可以说出口的话\n(Transition: Snare drum build and rising synth pitch lead directly into the final chorus drop.)\n\n[chorus]\n(Hook-Recall: Main vocal hook returns with maximum energy and layered ad-lib harmonies.)\n(Melody-Harmonic-Tension: Same harmonic structure as the first chorus, but intensified by the added vocal layers.)\n(Melody-Contour: Same contour as the first chorus, but delivered with ultimate power and intensity.)\n(Inst: All instrumental elements at maximum energy. An additional high-octave synth lead is layered over the arpeggio.)\n(Vocal-Perf: Forte, powerful delivery with layered backing harmonies and soaring ad-libs.)\n(Chords: G#m - E - B - F#)\n你是我钝感练习里 唯一的漏洞\n越想不在乎 越在乎得清醒\n所有的无所谓 碰到你就穿帮\n原来我根本 没练成过",
  "cover_prompt": "生成一张无字音乐专辑封面。风格严格参照 20 世纪 Color Field Painting（色域绘画），如 Mark Rothko 晚期作品的色层叠压逻辑与 Helen Frankenthaler 的浸染法（soak-stain technique）。画面的核心色彩与情绪：大面积冷钢蓝与消色灰在画布中央形成缓慢渗透的交界带，边界处被一道窄而温热的赭红色渗入——那道赭红像一条裂缝，克制却刺破整片冷静，象征所有「练习不在意」最终被某人击穿的瞬间。\n技法要求：色彩之间的过渡必须模拟颜料在未上浆的粗纹棉布（raw cotton canvas）上自然渗透、晕开的效果，边界柔软但保留颜料浓度不均匀造成的自然深浅变化（pigment pooling）。画面需要呈现真实画布的编织肌理（woven canvas texture），局部可见稀薄处透出的底布纹路。整体色调偏低饱和、微微发灰（muted, desaturated palette），避免荧光感和数字渐变的均匀平滑。\n绝对禁止：任何文字/字母/拼音、人物或人物轮廓、具象物体、几何图案、锐利边缘、胶片颗粒滤镜、3D渲染质感。",
