The piano, as a musical instrument can appear in dreams when you are becoming more free in expressing your passion. It embodies the idea of harmony and how and where it appears can describe where balance needs to be achieved. It can also relate to your mood depending on what type of music is being played. If the music is harsh or out of key, you may need to 'tone' how you are approaching experience - either up or down, as in lighten up or get more involved with what you are doing. See also Music.
