With rock and roll coming into place, a watershed moment occurred between 1962 and 1964 when the Surfaris released "Wipe Out", as well as when Ringo Starr of The Beatles played his Ludwig kit on American television. As rock moved from the nightclubs and bars and into stadiums in the 1960s, there was a trend towards bigger drum kits. The trend towards larger drum kits took momentum in the 1970s with the emergence of progressive rock. By the 1980s, widely popular drummers like Billy Cobham, Carl Palmer, Nicko McBrain, Phil Collins, Stewart Copeland, Simon Phillips and Neil Peart were using large numbers of drums and cymbals. In the 1980s, some drummers began to use electronic drums.
The second biggest factor that affects drum sound is head tension against the shell. When the hoop is placed around the drum head and shell and tightened down with tension rods, the tension of the head can be adjusted. When the tension is increased, the amplitude of the sound is reduced and the frequency is increased, making the pitch higher and the volume lower.
Drum muffles are types of mutes that can reduce the ring, boomy overtone frequencies, or overall volume on a snare, bass, or tom. Controlling the ring is useful in studio or live settings when unwanted frequencies can clash with other instruments in the mix. There are internal and external muffling devices which rest on the inside or outside of the drumhead, respectively. Common types of mufflers include muffling rings, gels and duct tape, and improvised methods, such as placing a wallet near the edge of the head. Some drummers muffle the sound of a drum by putting a cloth over the drumhead.
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.
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.
