A Bass drum is a large drum that produces a note of low definite or indefinite pitch. Bass drums are percussion instruments and vary in size and are used in several musical genres. Three major types of bass drums can be distinguished. Bass drums are percussion instruments and vary in size and are used in several musical genres.
A bass drum is typically cylindrical with the drum's diameter much greater than the drum's depth. There is normally a struck head at both ends of the cylinder. The heads may be made of calfskin or plastic. There is normally a means of adjusting the tension either by threaded taps or by strings. Bass drums are built in a variety of sizes, but size has little to do with the volume produced by the drum. The size is chosen is based on convenience and aesthetics.
The "bass line" is a unique musical ensemble consisting of graduated pitch marching bass drums commonly found in marching bands and drum and bugle corps. Each drum plays a different note, and this gives the bass line a unique task in a musical ensemble. Skilled lines execute complex linear passages split among the drums to add an additional melodic element to the percussion section. This is characteristic of the marching bass drum—its purpose is to convey complex rhythmic and melodic content, not just to keep the beat. The line provides impact, melody, and tempo due to the nature of the sound of the instruments. The bass line usually has from as many as seven bass drums to as few as two. But most high school drumlines consist of between 3 and 5. Bass drums used in such ensembles are usually those that use 2 mallets (formerly scorch bass drums, to distinguish them from those bass drums that formerly used one mallet, known in the 1930s as standard bass drums).

The xylophone "sound, voice",meaning "wooden sound") is a musical instrument in the percussion family that consists of wooden bars struck by mallets. Each bar is an idiophone tuned to a pitch of a musical scale, whether pentatonic or heptatonic in the case of many African and Asian instruments, diatonic in many western children's instruments, or chromatic for orchestral use.
The term xylophone may be used generally, to include all such instruments, such as the marimba, balafon and even the semantron. However, in the orchestra, the term xylophone refers specifically to a chromatic instrument of somewhat higher pitch range and drier timbre than the marimba, and these two instruments should not be confused.
The term is also popularly used to refer to similar instruments of the lithophone and metallophone types. For example, the Pixiphoneand many similar toys described by the makers as xylophones have bars of metal rather than of wood, and so are in organologyregarded as glockenspiels rather than as xylophones. The bars of metal sound more high-pitched than the wooden ones.
