For some time I have been looking for a word that describes a repetitive or monotonous task in a positive light. In particular, some people find simple tasks like grocery shopping, counting pennies, or making highly detailed drawings to be soothing. The closest thing I've found to such a word is the phrase 'comfortingly repetitive.' Synonyms for 'monotonous,' 'comforting,' 'soothing,' and 'repetitive' have turned up nothing close.
A vaguely related word might be 'stereotypy,' though this word is a noun that (negatively) describes a pathological behavior, whereas I am looking for a positive adjective. Maybe someone with a stereotypy would describe the tasks they do using the sought-after word.
A noun for a 'comfortingly repetitive task' would also be helpful, so long as it had a positive connotation.
