There's a lot to be said for tradition when it comes to the bass guitar, and it's a tradition that ultimately goes back to the originals: the Jazz Bass and Precision Bass. With some stellar options available from Fender and Squier, you're in a good place to get started with those iconic bass guitars. On the other hand, if you'd prefer something a bit more unique, you've got no shortage of options. Over the years, the bass guitar market has grown hugely, and there are now a ton of choices ranging from beginner-friendly instruments like Rogue and Dean models all the way to professional masterpieces from luthiers such as Warwick, Schecter and Rickenbacker.
Bassists often play a bass line composed by an arranger, songwriter or composer of a song—or, in the case of a cover song, the bass line from the original. In other bands—e.g., jazz-rock bands that play from lead sheets and country bands using the Nashville number system—bassists are expected to improvise or prepare their own part to fit the song's chord progression and rhythmic style.
To keep proper pitch across all frets in a multi-scale bass guitar, a fanned fret design is applied to the fingerboard. In this case, the frets extend from the neck of the instrument at an angle, in contrast to the standard perpendicular arrangement in standard neck designs, in which the fret spacing is wider for the long scale and closer for the short scale. This is not to be confused with perfect intonation across the whole neck, which is a feature of true temperament frets. Proponents of multi-scale and fanned frets designs also claim benefits such as comfort and better ergonomics.
Detuners, such as the Hipshot, are mechanical devices the player operates with the thumb on the fretting hand to quickly retune one or more strings to a pre-set lower pitch. Hipshots typically drop the E-string down to D on a four-string bass. Rarely, some bassists (e.g., Michael Manring) add detuners to more than one string, or even more than one detuner to each string, so they can retune during a performance and access a wider range of chime-like harmonics.
Many drummers extend their kits from this basic configuration, adding more drums, more cymbals, and many other instruments including pitched percussion. In some styles of music, particular extensions are normal. For example, rock and heavy metal drummers make use of double bass drums, which can be achieved with either a second bass drum or a remote double foot pedal. Some progressive drummers may include orchestral percussion such as gongs and tubular bells in their rig. Some performers, such as some rockabilly drummers, play small kits that omit elements from the basic setup. Some drum kit players may have other roles in the band, such as providing backup vocals, or less commonly, lead vocals.
Drums are used not only for their musical qualities, but also as a means of communication over great distances. The talking drums of Africa are used to imitate the tone patterns of spoken language. Throughout Sri Lankan history drums have been used for communication between the state and the community, and Sri Lankan drums have a history stretching back over 2500 years.
