7 Common Problems with Learning Sweep Picking and What to do About Them
by Mike Philippov
Sweep picking is considered by many to be a technique that separates average players from highly advanced players. Unfortunately, there are many challenges to be overcome with this technique before one can successfully adapt it as part of his or her style.
First, for anyone who may not know, sweep picking is a technique used by guitarists to play arpeggios. It is typically done when using distortion, but this technique is also used in other styles when clean guitar sound is used. The use of distortion makes it very challenging to play arpeggios quickly and cleanly.
In this article, I will present several of the most common problems that I have seen many people run into with sweep picking. Based on my own experience as a player and after replying to dozens of e-mails on this topic from students all over the world, I noticed that many students seem to be experiencing many of the same problems. Of course there are also likely to be issues that are specific to each student, but these questions are best addressed in person with a competent teacher.
So there are 7 main problems that I believe prevent many students from either learning sweep picking at all, or (for those who are more advanced,) with using this technique in expressive ways. Not all students have every one of these same 7 problems of course, (most have various combinations of them), but I think that by listing them all here, it will help more people to become aware of ways to improve their playing even if a specific problem may not apply directly to them.
These problems are:
 1) Practicing too fast
  Yes, this is common sense advice that we’ve all heard a million times, 
  right? However, even though this advice is commonly heard, it is shocking how 
  many people either choose to ignore it, or simply are not aware that they are 
  practicing way too fast because the general words such as “fast” 
  or “slow” are often misleading and meaningless because they mean 
  different things for different people. Just remember this (as a general guideline), 
  if you are practicing and your playing sounds sloppy, inconsistent in quality 
  and filled with mistakes, then chances are you are practicing much too fast. 
  Just remember that you can play ANY combination of notes perfectly if you play 
  slowly enough. If you keep trying to increase the speed but your playing is 
  full of mistakes and sloppy string noise, then you are just learning to play 
  sloppily. On the other hand, if you play slowly enough to play without mistakes 
  and you only increase the speed once you are sure that you can do so without 
  sacrificing the quality of your playing, you will be teaching your hands to 
  play the technique perfectly. So this piece of advice is twofold: first play 
  slowly enough to play without mistakes. And second: only increase the speed 
  once you are sure that you will not be sacrificing accuracy. 
Is this piece of advice common sense and common knowledge to most people? Of 
  course it is. But is this also one of the most common things to see guitarists 
  doing wrong? You bet it is! For example, we all know that exercise and working 
  out is good for our health (this is common knowledge) but how many people actually 
  DO exercise on a regular basis? So this means that even though the need to practice 
  slowly is obvious to most guitarists, many of those who struggle with their 
  progress would benefit greatly by slowing down their playing and focusing more 
  on accuracy. I hope you are starting to see where I’m going with this.
  
  2) Not paying attention to muting of the strings
  This is a very common problem that makes itself especially evident with sweep 
  picking. What do I mean by this? Well, the main goal of sweep picking is to 
  only have one note of the arpeggio sounding at any one time with the other notes 
  being completely muted (this is the only way to get the arpeggios to sound clean 
  and precise when playing with a lot of gain and distortion). There are two main 
  ways of going about this: either to use the palm of your hand to mute the strings 
  you are not playing (this method is the most common and is used by players such 
  as Rusty Cooley, Michael Romeo  and Yngwie Malmsteen) and to use the thumb of 
  the picking hand to do the same thing (this method is used by virtuosos such 
  as George Bellas and Tom Hess) The main point here is to pay attention to how 
  effective your muting technique is (regardless of which of the two methods you 
  choose to use) and evaluate its effectiveness by LISTENING to how clean your 
  playing actually is when you play slow and when you play fast. The best way 
  to do this is to either record yourself or to ask for honest and unbiased feedback 
  from your teacher about your playing. If your playing is not as clean as you 
  would like it to be, then I highly recommend paying careful attention to the 
  way you mute the strings and perhaps change your technique a bit if necessary 
  to fix that problem.
3) Trying to “strum” the arpeggios with the right hand 
  instead of hitting each note individually
  When sweep picking, each note should have definition and rhythmic placement. 
  If you simply strum or rake the pick across the strings, the notes will sound 
  sloppy and out of time. You need to make sure that each note has definition 
  and you should be able to play the arpeggio slowly to a metronome and have it 
  be in time. The arm moves in a continuous motion across the strings but each 
  note must have definition. 
4) Not isolating the “rolling” motion of the left hand 
  to practice it exclusively until it is no longer a challenge.
  If you have spent any amount of time trying to learn sweep picking, then you 
  have most likely encountered (or at least heard about) the technique of “finger 
  rolling” that is used in some arpeggio shapes. This challenging aspect 
  of the technique is one of many topics thorougly discussed in the The 
  Ultimate Sweep Picker's Guide. The best way to tackle the rolling technique 
  is to isolate it and practice just the rolling motion by itself until it no 
  longer poses a challenge. Make sure to practice slowly of course and avoid having 
  the notes ring together (this is a very common problem) Many players simply 
  play the arpeggios that contain the rolling technique up and down hundreds of 
  times in hopes that the problem will simply solve itself. But you will be MUCH 
  more effective if you are able to get specific about the nature of the problem 
  (see this 
  article). In this case, the problem is the rolling itself, not necessarily 
  the rest of the arpeggio, so by focusing your attention only on the problem 
  you save yourself time and are able to be much more effective in your practice. 
 5) Not making the pull off at the top of each arpeggio articulate 
  enough.
  Many arpeggio shapes require you to perform a pull off at the top of the shape 
  (usually on the high E string). Many players make the mistake of letting the 
  pull off sound way too weak compared to the other notes of the arpeggio (which 
  are picked). This creates an unevenness in volume and the arpeggio lacks precision 
  and rhythmic control. What I recommend is spending a bit of time only on the 
  pull off part of the arpeggio and practice making the pull off as LOUD as you 
  can (of course I'm referring to how strong your pull off itself is, not to how 
  loud you can turn up the amp). When you do this, you will notice a big difference 
  in your arpeggio playing.
 6) Not learning how to build chords and arpeggios and how to use them 
  in a musical way.
  Do you know what the word “arpeggio” means? Do you understand the 
  principles of chord construction and how chords are grouped into keys? Can you 
  name diatonic triads and diatonic seventh chords in any key? Do you understand 
  the concepts of voice 
  leading? The answers to these questions can GREATLY help you expand your 
  creativity with sweep picking. Many players learn several arpeggio shapes and 
  may even be able to play them up and down pretty quickly and cleanly. However 
  without knowing how arpeggios can be used in different musical contexts such 
  as soloing or songwriting, that player will be stuck playing the same shapes 
  in the same way for months and years. These problems can easily be prevented 
  and fixed by studying music theory and chord construction. For some beginning 
  resources, check out this free Music 
  Theory Master Class as well as this article: Voice 
  Leading Part 1.
  7) Only using standard shapes and limiting the creative potential of this technique
  It is unfortunate that many players box themselves into using only simple major/minor/diminished 
  arpeggios in ways that have already been done many times. There are so many 
  other ways in which this technique can be used creatively. Some of the most 
  obvious ways include the use of seventh chords in combination with triads, extending 
  arpeggios using tapping, using different picking/articulation techniques to 
  play the arpeggios, and connecting the shapes using the principles of voice 
  leading. Many of the creative approaches can be discovered by studying chord 
  theory and knowing the names of all the notes on the fretboard. This will help 
  spark ideas for how sweep picking can be used in more expressive ways that will 
  help you enhance your songwriting. Then you will not need to search the web 
  for “sweep picking licks”, because you will be able to come up with 
  your own creative ways of using the technique to express yourself.
At this point, we have looked at several problems that guitarists typically have with learning this elusive technique. What should I do now, I hear you ask? Well, if you don’t think you have any of the above problems, then great, you’re on the right track! But if you think that some of these points can apply to you, then you now know what you need to work on to take your playing to the next level.
