Alternate Picking Lesson How do players like Yngwie Malmsteen, Al Di Meola, Steve Morse and Paul Gilbert pick so quickly and cleanly? Hyper speed picking abilities are the product of a logical, pragmatic technical approach based on economy of movement-playing the most notes with the least amount of effort. This primer will help you think in these terms. With this mind-set, you'll be able to build an arsenal of smooth, fast, picking licks that you can execute even on your worst day. To get started, grab a freshly-minted plectrum (pick) and hold it between your thumb and index finger with the pointed end facing the strings. Even though this standard grip seems the most logical way to hold the pick, some speed demons do it differently: Eddie Van Halen holds the pick between his thumb and middle finger; James Hetfield and Steve Morse use a three-fingered grip (thumb, middle and index); and Pat Metheny picks with the rounded side of the plectrum. If you play better using an unorthodox grip, go ahead-you can't argue with success. Now rest the heel of your palm on the strings in front of the bridge. This technique is called "palm muting". The more pressure you apply, the "chunkier" your sound will be. For lightning runs, a light pressure will allow the strings to ring, but will cut unwanted noise. Where you pick is also important: picking right in front of the bridge produces a trebly twang, whereas picking closer to the neck creates a softer, mellower tone. The angle at which you attack the strings also effects your sound. Holding the pick parallel to the strings and plucking produces the clearest attack. "Slicing" the string at an angle yields a less-defined attack. If you're sitting down, anchor your right forearm to the guitar's body for added control and stability. If you're standing up, the angle between your wrist and arm will depend on the length of your strap. Adjust your strap to where you're the most comfortable. Don't put the guitar lower than you can handle: no matter how cool you look walking out on stage with the guitar around you knees, the spell will be broken the moment you try to play something in that awkward position. You can also anchor your pinky on the pickguard to help maintain stability and provide your hand with a close point of reference. Experts disagree about the benefits of anchoring your hand in this way, so if it doesn't feel right, don't do it. Now that you've achieved the perfect picking posture, you're ready for the two basic alternate-picking moves" the upstroke and downstroke. The moves are easy, but getting them to flow quickly and smoothly is the trick to attaining warp speed. Some players favor the stiff-wrist approach, which restricts all movement to the elbow joint. The circular motion approach, employing only the thumb and index fingers, is another technique. But most players get the best results by initiating all movement in their wrist. Use the technique that feels the most natural to you and always remember to keep your wrist relaxed. If you feel any pain during a workout, stop immediately. Pain is your body's way of telling you that you're doing something wrong. Stop and rest. If the pain or soreness persists, see an orthopedic specialist to make sure you aren't developing tendinitis. The most effective alternate-picking exercises are short, repeating patterns that focus on one particular type of maneuver. Figure 1 is a good beginner-level exercise for developing a smooth coordinated tremolo picking technique. Practice this exercise at a moderate tempo (80-100 beats per minute) with a drum machine or metronome and try to keep the picking motion on an even, back and forth plane without leaping over the string. Relax your right hand as much as possible while gradually increasing speed. Watching your picking in a mirror is a bio-feedback technique that can really help you relax. Gradually increase the tempo as you get better. You're smokin' if you can perform this exercise at 160 beats per minute. Don't forget to always use a clean tone (no distortion). h hammer on p pull off \ slide down / slide up tr trill u upstroke d downstroke Figure 1 d u d u d etc |-0--0--0--0--3--3--3--3--4--4--4--4--7--7--7--7-|-8--8--8--8--11--11--11--11 |------------------------------------------------|-------------------------- |------------------------------------------------|-------------------------- |------------------------------------------------|-------------------------- |------------------------------------------------|-------------------------- |------------------------------------------------|-------------------------- -12--12--12--12--15--15--15--15-|-16--16--16--16--15--15--15--15--12--12--12 --------------------------------|------------------------------------------- --------------------------------|------------------------------------------- --------------------------------|------------------------------------------- --------------------------------|------------------------------------------- --------------------------------|------------------------------------------- -12--11--11--11--11-|-8--8--8--8--7--7--7--7--4--4--4--4--3--3--3--3------|| --------------------|-----------------------------------------------------|| --------------------|-----------------------------------------------------|| --------------------|-----------------------------------------------------|| --------------------|-----------------------------------------------------|| --------------------|-----------------------------------------------------|| Figures 2-4 are some cool, easy-to-execute, single string speed licks, designed to help improve your left/right hand synchronization. As you become familiar with each one's fingering pattern, try moving in onto another string. Every string feels different-not only are they different thicknesses, your pick attacks them at different angles. These kinds of licks are not only easy to pick at high speeds, they also sound (and look) impressive. Once you feel comforatble performing them quickly, you're ready for string-crossing.

String crossing is substantially more complicated. The goal is to arrange all the string crosses so they feel natural and comfortable. The number of notes to be played on each string and the direction of your first picking stroke (up or down) determine how easy or difficult a pattern is to pick. With a bit of thoughtful experimentation, you'll be able to find those patterns that work well for fast alternate picking-and weed out those that don't. Figures 5A-C show three different ways to pick the same lick. The first way (fig 5A) is the most laborious for the right-hand-it requires the pick to make four awkward string crosses. Figure 5B shows a much smoother, easier way to pick the same run. Notice that there are only two string crosses. Figure 5C is the easiest. The E note moves over to the 3rd string and the whole pattern begins with a downstroke, enabling you to best accent the downbeats for a strong, forcefull attack.

Though this fingering approach may look like it makes the most sense, it often proves to be very awkward for fast, alternate picking-especially when descending. I've found that during the descent, most seven-note scales can be picked more smoothly and easily by employing an alternate left-hand fingering. Let's use the G major scale as an example. Figure 11 depicts its standard two-octave, fingering pattern. If you're like me, your picking hand probably gets tied up in knots when trying to quickly descend this pattern.

The ascending pattern is similar to that in Figure 11. The descending pattern, however, is quite different. Note the use of finger slides and position shifts. Even though this may seem, like an odd way to finger a scale, you'll find that it enables your right hand to maintain a smooth, alternate-picking motion without having to muscle across the strings.

Figure 13 is a chromatic scale pattern that uses finger slides on the 1st and 6th strings to maintain a smooth picking pattern. Note that the entire fingering pattern is shifted up one fret on the descent.

This creates an optimum string-crossing pattern for the right hand, enabling you to soar through several octaves while conserving precious picking energy. Figure 21 is a monstrous, two note-per-string F major arpeggio that transports your left hand from the 1st to the 20th fret and back. Beginning with an upstroke, proceed slowly at first and concentrate on shifting your left hand smoothly while maintaining a strict alternate picking motion.

The trick is to find a fingering pattern that enables your right hand to flutter back and forth with a minimum of effort. The ascending and descending triplet licks in Figures 27 and 28 are a perfect example of this concept. The easiest way to pick the ascending lick (fig 27). is to alternate between playing three consecutive notes on the 2nd string and three notes on the 1st string. The descending lick (fig 28), however, is more easily picked by alternating between two notes on the 1st string and four notes on the 2nd string. Note the use of finger slides on the 2nd string.
