What are the similarities between haiku and tanka?

Haiku and tanka are both traditional forms of Japanese poetry that emphasize brevity and nature. Each form employs a specific syllable structure, with haiku consisting of 17 syllables arranged in a 5-7-5 pattern, while tanka extends this to 31 syllables in a 5-7-5-7-7 format. Both forms often explore themes related to seasons, emotions, and the human experience, fostering a deep connection to nature and the moment. Additionally, they both rely on evocative imagery and subtle suggestion rather than explicit statements.
