Sure, here's a chord progression in the key of D minor for a 4-bar music piece about Japanese Anime featuring a cello:
| Dm | G | C | F |
This chord progression uses the I, IV, V, and vi chords in the key of D minor. The Dm chord is the tonic chord, the G chord is the subdominant chord, the C chord is the dominant chord, and the F chord is the relative major chord. These chords create a sense of tension and resolution, making them a great choice for creating an emotive and dramatic sound.
In terms of the cello, you can play the melody on the upper register and use the lower register to play the chords, creating a full and rich sound. Additionally, you can use techniques such as vibrato, pizzicato and harmonics to enhance the sound.
Finally, it's worth noting that the chord progression you've chosen can create a melancholic and contemplative mood, which may fit well with the theme of Japanese anime.
