But without the ability to bring those imagined sounds into the real world, one's creative aspirations will remain crippled. Training one's ears to understand and recognize musical sounds and concepts is one of the most vital ways to fortify the connection between the musical ideas in one's mind and the musical sounds created on one's instrument.

All musicians practice ear training constantly, whether or not they are cognizant of it. If, when listening to a piece of music, a musician is envisioning how to play it or is trying to play along, that musician is using his or her ear-the understanding and recognition of musical elements-for guidance. This is also true when trying to emulate a piece of music, or transcribe it, or even just finding inspiration in it. No matter what one is playing, one?s ear is the navigational device that steers the musical ship where it will go. Without a good ear at the helm, you could find yourself musically adrift at sea.

I have always been fascinated with looking at music written on paper. When I was in college, I took a class called solfege, which entailed learning how to sight-sing. Sight-singing is the art of looking at a piece of written music and singing it. First, you identify the key center, and then you sing the written pitches, using the doe-ray-me phonetic structure, just like that song in the movie The Sound of Music. Do-Re-Mi-Fa-Sol-La-Ti-Do (pronounced Doe-ray-me-fa-so-la-tee-doe) represents a major scale; there are other monosyllabic sounds that represent the other pitches that reside within a 12-tone octave.

These solfege classes in college were difficult courses, but they were well worth the time invested. A thorough study and analysis of solfege within the confines of this column would be impractical, so I can only encourage you to investigate it on your own.

Many musicians do not have the ability to pull the sounds-guitar solos, rhythm parts, melody lines, etc.-off the records that they love. Transcribing is an art that takes a lot of practice and a study that I encourage everyone to experiment with.

But fear not: you do not need to have the ability to sight-read or transcribe in order to practice ear training exercises. If you are just sitting there with a guitar, there are still a great many ways to develop your ears, in the quest to strengthen the connection between your head and your fingers. Below, I have outlined some of the ways a guitarist can work on ear training exercises using just the guitar.

As guitarists, there are certain things that most of us do that are simply part of the program: we learn some scales, develop some exercises intended to improve our physical abilities, work on chord forms on different parts of the neck, etc. I believe it is extremely important to put aside some time dedicated solely to focusing on ear training.

One of the easiest ways to begin working on ear training is to sing what you play. For example, you can play a C major scale (C D E F G A B) in any position-preferably one that is physically comfortable for you-and sing each note of the scale as you play it, being very careful to sing on pitch as accurately as possible. Start with one note: play the note, sing it, and then play and sing the note simultaneously. Then go to two notes. Once you feel comfortable, take a little piece of that scale, say, the notes C, D, E and F, and create a very simple melody with these notes for you to sing simultaneously, la jazz guitarist George Benson.

This is an easy way to get your ear in sync with the sounds your fingers are creating. Whether you?re soloing over a rhythmic vamp or are playing alone in free time, you have to really stick with it, and don't allow yourself to slip up or drift into something else. The idea is to endlessly improvise and sing what you are playing, using any key.

Another good thing to do is to record a simple one-chord vamp to play over. First, only play/sing notes that fall within the key, staying within a basic note structure of a five-, six- or seven-tone scale. Don?t start wandering off into your favorite guitar licks to play; save that for another time, when you've developed your ear to the point where you can sing just about anything you can play.

This is an exercise in discipline: do not play anything that you cannot follow perfectly with your voice. Whether you stay within one octave of the guitar, or you sing the notes an octave lower than the sounding pitches, or you use falsetto to hit the high notes, you must be able to recreate all of the notes played on the guitar with your voice.

If you work on this every day, you'll find yourself getting better and better at it, and it will become easier to do. The cool thing that happens is that you'll begin to hear music more clearly in your head, allowing you to formulate musical ideas-write music-within your head, without the aid of a guitar. When you finally do pick up the instrument, you will discover that you will instinctively be able to play these ideas that have taken form in your mind.

To take this a step further, try this exercise: without a guitar at your disposal, picture the guitars fretboard in your mind, and then envision playing something so that you will hear and see the notes as they are played. It may be helpful to sing the notes as you imagine them being played.

This is an excellent exercise that will fortify your mind-fretboard relationship and actually improve your ear by strengthening the acknowledgment of pitch relativity (how one pitch relates to another, in terms of sound and placement) on the guitars fretboard. You may discover some cloudy areas in your minds eye/ear, but if you work through it, the picture will soon become clearer and clearer.

These techniques do not address the act of playing one thing on the guitar and singing something completely different. Someone like Jimi Hendrix had the uncanny ability to play very complex rhythm parts and single-note riffs while singing complementary parts. This technique requires a whole different set of brain muscles and is very difficult for many players. Playing one thing while singing another must be worked on as an independent field of study.
