A Cruel Angel's Thesis Piano Tutorial

📊 Level: Intermediate

The verse is friendly, but the full piece quickly turns into an energetic anime arrangement. Early bars use a clear melody over half-note harmony, then later sections switch to steady eighth-note bass motion and thicker chord hits around bars 32, 56, and 80. You need solid timing more than raw speed at first.

✋ Left hand

The left hand starts with broad supporting chords, then settles into repeating eighth-note drive. Around bars 16-32 it rocks between low D octaves and short chord punches, and that groove comes back later. Practice those bass patterns alone until they feel automatic, because they are the engine of the song. Keep the wrist loose so the repeated low notes do not get heavy.

🤚 Right hand

The melody is punchy and vocal, with repeated Bs, quick pickups, and short chord shapes. Later, the right hand becomes more chord-based, especially in bars 56-64 and 96 onward, where the tune is hidden inside fuller voicings. Sing the top note while you play so the melody stays clear.

🔎 Be aware of

There is a real jump in energy after the slower opening, so do not practice the whole piece at one speed.

🎯 Biggest challenge

Locking the bright right-hand melody to the left-hand eighth-note groove once both hands get busier.

⚡ How to practice it

1. Learn bars 1-16 as melody plus bass only.
2. Loop one left-hand pattern at a time before adding chords above it.
3. In chord sections, bring out only the top note first.
4. Practice the tempo jump separately before connecting sections.

A Cruel Angel's Thesis is the opening theme of Neon Genesis Evangelion, sung by Yoko Takahashi and first released in 1995. Even people who have never watched the series often recognize it because the song became inseparable from Evangelion's mix of teenage emotion, high drama, and striking imagery.

What makes it stick is the contrast. The melody is bright, direct, and almost triumphant, while the world around it is anxious and psychologically heavy. That tension is a big part of why the song has lasted so well: it feels energetic on the surface, but it also carries a sense of urgency that fits the series perfectly.

On piano, that combination works especially well. The tune is instantly singable, and the harmony gives you room to shape the music from light and driving to dramatic and full. It is a strong tutorial piece because the melody needs clear phrasing, while the accompaniment can build the same momentum that makes the original opening so memorable.
