tunelessly

The word 'tunelessly' is built upon the core concept of a 'tune', which traces back to the Greek 'tonos', signifying tension and, by extension, a musical pitch. The addition of the Old English suffix '-less' transforms it into an adjective meaning "devoid of a tune." Finally, the adverbial suffix '-ly', also of Old English origin, specifies the manner of an action. Thus, the literal progression from "tone" to "without a tone" to "in a manner without a tone" clearly illustrates the word's logical construction for describing an action performed without melody or musicality.
