Since the 1980s, digital samplers have enabled editing of recorded sounds, leading to widespread use of sample sounds such as bicycle bells and daily noises in music production. While sample sounds often emphasize mood or theme, they are rarely used as lead sounds, which carry the lead sounds. Due to the irregular nature of sample sounds, existing software struggles with precise pitch and time adjustments. In this paper, we propose a method and implement a system to generate effectively and easily a musical piece by using a sample sound as lead sounds. This system checks whether the speed and pitch of a given musical piece and a sample sound can be adjusted to check for an arbitrary musical piece and an arbitrary sample sound, and if possible, generate the music. This study seeks to expand the role of the sample sound in music production and create new acoustic experiences.
