"The essence of groove may be hard to identify, but one thing's for sure: you know when your music doesn't have it."
10 ways to give your music groove http://www.musicradar.com/us/tuition...-groove-232242
There are quite a few postings/questions about the "groove
" at TalkBass.
I understand how important it is for the bass players, but to my regret, I could not find any threads asking/talking about the "length of notes
played in the groove". For some reason, I always wanted to get some kind of answers about it.
I decided to look on the Internet but could not find a lot of info.
Once again, there was only one book about "Bass Grooves
" by Ed Friedland http://www.amazon.com/Bass-Grooves-D...8065050&sr=1-3
(It so strange, the bass players talk so much about the groove, but there is only one, very good, but only one book
about it on the market.)
From Ed's book:
“Where you stop the note is just as critical to the overall feel. Optimum note length depends on several factors: Tempo, the level of rhythmic activity, the amount of “bass energy, and stylistic aesthetics all co contribute to defining effective note length and more....."
The following are some links about the groove/swing that I found on the internet, mostly for computer musicians:
“The length and strength of notes is almost as important to a groove as their actual placement.” http://www.musicradar.com/us/tuition...-groove-232242
“Bassists know that the player who grooves will work the most. Bassists also know that a groove grows from a magical combination of attack, sustain, and release. Whether jazz, rock, country, or funk, there is always a basic pulse, and we create a groove by stating parts of that rhythmic pulse—playing notes—and implying other parts of the pulse by added rests.” http://www.bassplayer.com/article/jo...art-one/151646
“Playing a great groove is not about playing all of the notes, it’s how one plays the best notes. Easy, right?”
“Trumpeter Nicholas Payton has written about the groove conundrum in his blog: “Swing is elusive. The harder you try to swing, the less you swing.” Or as pianist Hal Galper described the goal of effortlessness, “Playing music is supposed to be easy! Most of us think it’s supposed to be hard to play, but truthfully, you can’t play music well if it’s hard to do. If you can’t do it easily, you can’t have fun and project that feeling of fun to your bandmates and listeners.” [IAJE Journal interview with Hal Galper, 1990].” http://www.bassplayer.com/article/jo...art-two/152043
“…a good groove sounds easy. If a bass line sounds hard, then it’s probably not really grooving.
“So what is swing really? Is it all timing? No, it is not just the timing or the Note-On strike, it is as much about the note end point (“gate time” or duration) and it certainly is influenced by volume (controlled by “velocity” in computer chip-based products). Timing, Velocity and Gate (duration) are the keys to what we consider swing and feel.
Gate time, the duration of a held note, can be critical
One of the things I learned playing with legendary bassist, (the late great) Bernard Edwards of Chic fame, was just how much a bass line could swing all by itself. Now I’m not necessarily talking jazz swing here, Bernard was very much out of the James Jamerson school of R&B and Funk bass playing. But it applies to jazz swing as well. How you deaden certain notes and how you let others ring can setup its own rhythmic “thing” within the groove. Often on a song that ‘Nard had written or was arranging, he would play just the bass line for you and you could hear where everything was supposed to go – because the spaces were as important as the notes that were played. It was a skill that not many have on this level. But from just the bass line you could hear where the drums would go, where the guitar would fit and where the keyboards would go. The ‘ghost’ notes, the thumps and the knocks were all important. Guitarist Nile Rodgers (also from the Bronx, by the way) and I would be able to voice so-called “jazz chords” over top of the bass line – giving the music a sophisticated feel. This was back in the pre-Chic, “Big Apple Band” days (circa 1974-76) Bernard and Nile would work out very intricate rhythmic interplay that eventually blew up into “the hook” for many a song. Guitar and Bass grooves – spend some time with the various arpeggio patterns in the Motif XS – by offsetting timing, altering gate time, velocity and swing quantize you will be able to come up with an endless resource of material.
I like to think of the Gate time as the “attitude adjustment”. Swing Quantize will offset the upbeats by delaying their timing… giving the feel of holding back, then catching up. And Velocity alterations can be important in hiding some events and bringing other to the front. Attitude adjustment – like walking with an attitude versus marching… while marching is some how “stiff” and rigid, when you see (in the language of the old school music) a “cool cat” struttin’ down the avenue, there is a swing to it. Both types of walking are rhythmic and in time but one has a definitively stiffness to it, and the other a very “cool” laid-back attitude to it… like it has more components in motion… Swingin’ http://www.motifator.com/index.php/s...ur_music_swing
…projects with a swing feel, though they may be written entirely in eighth notes, are often played more like eighth-note triplets, with the first note extended and the second one shortened. The Swing option lets you distort the timing grid so each pair of notes is spaced unevenly, giving the quantized material a swing feel.
A swing value of 50 percent (the default) means that the grid points are spaced evenly. A value of 66 percent means that the time between the first and second grid points is twice as long as the time between the second and third points. The following figure illustrates the effect of the swing setting on the timing grid: http://www.cakewalk.com/Documentatio...ngMIDI.38.html
"Real musicians do not generally play exactly in time: they play with 'feel', where there can be 'microshifts' in timing. The snare might be slightly late on beats 2 and 4 ('laid back'), while the kick or the bass might be slightly early or 'pushed'
“Conventional 'swing' or 'shuffle' feel is where 'even' eighth or 16th notes are played as the first and third of a group of triplets. While this is 'correct' for slow tempos, as the tempo increases a triplet feel can end up sounding rather uneasy, so musicians tend to play the swung notes nearer to the 'even' timings”
“For more funky grooves, it can sound good to make accented second and fourth 16th notes slightly early.” http://www.soundonsound.com/sos/nov0...icworkshop.htm
“Swing ratios tend to get wider at slower tempos and narrower at faster tempos. Miles Davis varied his swing ratios, frequently delaying the first note of each pair of eighth notes by some milliseconds and then synchronized the second eighth note with the drummer's swing eighths being played on the cymbal. Advanced performers often lay back or play behind the beat when performing jazz melodies by delaying the rhythms by milliseconds.
Rhythms identified as swung notes most commonly fall somewhere between straight eighths and a quarter-eighth triplet pattern.
Quarter notes can sound swung when they are played slightly behind the beat, detached, and accented on the two and four, or late on one and three, but closer to the beat on two and four. Phrases swing when they begin between the beats, similar to how straight eighths can swing when they are behind the beat which creates an asymmetrical cross rhythm.” http://en.wikipedia.org/wiki/Swing_(...formance_style
