I have recently read some of my old stories (and some of my newer stories) and I have discovered that every single one has a very melancholic tone. I write pieces that are extremely emotional (perhaps a little try-hard at times), deep, and use poetic, thoughtful landuage. This in itself is alright. My issue however is that this is the only tone I seem to be able to write in. My stories all seem rather monotone, because I seem unable to write anything humourous, lighthearted, exciting, adventurous, joyful, sweet, touching or just plain silly. Everything is full of melancholy, nostalgia and a whole lot of boring, long-winded passges. So my question is, how do you write in different tones? Do you guys have any exercises or advise that might help. Thanks.
