When a floor tom is added to make a four-piece kit, the floor tom is usually 14" for jazz, and 16" otherwise. This configuration is usually common in jazz, classic rock and rock and roll. Notable users include Ringo Starr in The Beatles, Mitch Mitchell in the Jimi Hendrix Experience, and John Barbata in the Turtles. For jazz, which normally emphasizes the use of ride cymbal, the lack of second hanging tom in a four-piece kit allows the cymbal to be positioned closer to the drummer, making them easier to be struck.
A fill is a departure from the repetitive rhythm pattern in a song. A drum fill is used to "fill in" the space between the end of one verse and the beginning of another verse or chorus. Fills vary from a simple few strokes on a tom or snare, to a distinctive rhythm played on the hi-hat, to sequences several bars long that are short virtuosic drum solos. As well as adding interest and variation to the music, fills serve an important function in preparing and indicating significant changes of sections in songs and linking sections. A vocal cue is a short drum fill that introduces a vocal entry. A fill ending with a cymbal crash on beat one is often used to lead into a chorus or verse.
Specific bass brands/models became identified with particular styles of music, such as the Rickenbacker 4001 series, which became identified with progressive rock bassists like Chris Squire of Yes, and Geddy Lee of Rush, while the StingRay was used by funk/disco players such Louis Johnson of the funk band The Brothers Johnson and Bernard Edwards of Chic. The 4001 stereo bass was introduced in the late 1960s; it can be heard on the Beatles' "I Am The Walrus." 
Heavy metal bass players such as Geezer Butler (Black Sabbath), Alex Webster (Cannibal Corpse), Cliff Burton (Metallica), and Les Claypool (Primus, Blind Illusion) have used chime-like harmonics and rapid plucking techniques in their bass solos. Geddy Lee of Rush has made frequent use of bass solos, such as on the instrumental "YYZ". In both published Van Halen concert videos, Michael Anthony performs unique maneuvers and actions during his solos. Funk bassists such as Larry Graham began using slapping and popping techniques for their solos, which coupled a percussive thumb-slapping technique of the lower strings with an aggressive finger-snap of the higher strings, often in rhythmic alternation. The slapping and popping technique incorporates a large number of muted (or 'ghost' tones) to normal notes to add to the rhythmic effect. Slapping and popping solos were prominent in 1980s pop and R&B, and they are still used by some modern funk and Latin bands.
The long scale necks on Leo Fender's basses—with a scale length (distance between nut and bridge) of 34 inches (864 mm) — set the standard for electric basses, although 30-inch (762 mm) "short scale" instruments, such as the Höfner 500/1 "violin bass" played by Paul McCartney, and the Fender Mustang Bass are also common. Short scale instruments use the same E-A-D-G tuning as a regular long scale instrument. Short scale instruments are good choices for bassists with smaller hands, such as children or young teens who are just starting the instrument. While 35-inch (889 mm), 35 1⁄2-inch (902 mm), and 36-inch (914 mm) scale lengths were once only available in "boutique" instruments, in the 2000s (decade), many manufacturers began offering these "extra long" scale lengths. This extra long scale provides a higher string tension, which may yield a more defined, deep tone on the low "B" string of five- and six-stringed instruments (or detuned four-string basses).
After spending 29 hours researching 21 models and testing seven with a panel of professional and amateur pianists, we think the Casio Privia PX-160 is the best budget digital piano for beginners. It suitably replicates the feel of an acoustic piano and has some of the most realistic sounds we’ve heard in this price category, and its dual headphone outputs accommodate both student and teacher.
Since there are so many digital pianos worthy of your attention in this catalog, you may want to narrow down your choices using some of the search options on the sidebar. For example, if you select stage digital pianos under the category section, you'll be presented with all the digital pianos that were made for the stage. Once here you have the opportunity to drill down even further and can search by topics like number of keys, MIDI/USB Connections or by whether or not the digital piano has built-in speakers.
