Fast or slow?

Since I start my research, I have been working in fast music. “Other side…” for accordion solo, “Sonata for Violin and Piano”, “Colours (in circles)" for marimba and string quintet and “Colours (here in)” for choir are fast music (or a big part of them are). I think I should focus this work in engaging, creating, developing and transforming harmony and melody; and timbre and colour

I know there is lots of slow music in this world, but I think it is also important to make both (fast and slow). At this moment I feel I am doing to much fast music and making slow music is also good.
