Descriptions of my (personally invented) melody types

• non-musical: Not at all musical, like the drumming of a woodpecker or the cawing of a crow
• simple rhythmic: Simple melody with repeated notes but not the same tone, e.g. Firecrest
• stereotype melodic: A predictable melody, maybe with some variations, like the chaffinch's
• improvised melodic: An unpredictable melody like the blackbird's
• sings 30 seconds or longer: A song most easily categorized by its lasting 20 seconds or more, often with mimicry and short variable elements, e.g. song of the sedge warbler
• sings 5-19 seconds: A song most easily categorized by its medium length of 5-19 seconds, e.g. the European serin
• one note: Melody with one repeated note
• two notes: Melody with two repeated notes
