Medium

The instrumentation of the pieces is fairly similar. In the Cello Suite the Cello is unaccompanied throughout the entire prelude. However, Across the Universe feature male lead vocals, acoustic guitar,  tambura, maracas, sitar, and a string section. These mediums create unique tone colors. In Bach's piece the cello creates a warm timbre that causes the listener to feel relaxed when listening to the flowing rhythm of the piece.

The instrumentation of Blackbird includes a male vocalist and an acoustic guitar. Another sound that seems like a metronome is present in the piece, but is simply Paul McCartney tapping his foot while recording the guitar tracks. The simplicity of the mediums invokes a feeling of interest into the listener. The performers of these pieces are required to harmonize themselves whilst playing the melody.

These pieces could both be played by soloists.
