Trailer AI
予告編のサウンドを分析
予告編を構成するリズム・メロディ・サウンドの特徴をAIが分析し、あなたの楽曲に反映します。
リズム & テンポ
Trailer music follows a strict dramatic arc. Act 1: quiet, emotional, establishes mood (piano, strings). Act 2: builds intensity, introduces rhythm and brass. Act 3: full-scale climax with everything firing — choir, percussion, impacts. Optional button/stinger at the end.
メロディ & ハーモニー
Trailer music pioneered a unique sound design vocabulary — risers (building tension), hits (rhythmic impacts), booms (sub-bass explosions), braams (Inception-style horn blasts), whooshes (transition sweeps), and stingers (final punctuation). These elements are as important as the music itself.
サウンド & 音色
Every harmonic choice, dynamic shift, and timbral change is calculated to maximize emotional impact. Minor keys for drama, major for hope. Silence before impacts. Tempo acceleration toward climax. Trailer music is the most emotionally efficient music ever composed.
制作テクニック
Modern trailer music blends orchestral power with electronic production — synthesized bass, processed percussion, and sound design layered with live strings, brass, and choir. Companies like Two Steps from Hell, Audiomachine, and Immediate Music defined the genre.
予告編のサブジャンルを探る
予告編にはさまざまなスタイルが存在します。お好みのサブジャンルを選んで、AIで楽曲を生成しましょう。
Epic Orchestral Trailer
Full orchestra with choir, massive percussion, and brass. Two Steps from Hell and Audiomachine territory. Used for blockbuster action and fantasy films.
Emotional Drama Trailer
Piano-led, string-driven emotional builds. Indie film trailers, Oscar dramas, and bittersweet stories. Think slowed-down cover songs and intimate crescendos.
Hybrid Action Trailer
Electronic bass and beats fused with orchestral power. Dark Knight-style tension, Mad Max fury. Distorted synths meet brass stabs over pounding rhythms.
Horror Trailer
Slow, creeping tension with sharp stingers. Music box melodies, children's voices, reversed sounds, and silence weaponized for maximum dread.
Game Trailer Hype
High-energy builds designed for game reveal and launch trailers. Licensed-music energy meets custom scoring — dubstep drops, rock anthems, and orchestral power.
Teaser & Reveal
Short, atmospheric pieces for 30–60 second teasers. Minimal instrumentation building to a single reveal moment. Mystery first, spectacle later.
