How to Learn Guitar: A Beginner's Guide to Technique, Practice, and Tools

Anyone picking up a guitar for the first time faces the same early questions: how to hold the instrument, which chords to learn first, how much to practice, and which app or course to trust. Guitar maker Martin Guitar and the long-running free platform JustinGuitar.com both publish structured beginner guidance, and independent reviews of learning apps such as Yousician and Simply Guitar outline how digital tools fit into that process.

Posture and basic setup

According to Martin Guitar's playing guide, a seated beginner should use an armless chair or low stool, rest the guitar body on the thigh, and keep the neck angled upward while balancing it between the thumb and forefinger, maintaining a straight back. When standing, a strap attached to the guitar's strap buttons should hold the instrument over the non-dominant shoulder in the same body alignment used while sitting.

For equipment, Martin Guitar recommends a light string gauge, which is easier to press down and more comfortable for untrained fingertips, paired with a light-gauge, flexible pick. The pick should be held between the thumb and index finger of the dominant hand, with its tip at a right angle from the side of the thumb.

Fretting, strumming, and the first chords

Fretting technique, per Martin Guitar, means pressing a string just next to the fret wire rather than directly on top of it, using curved fingers so neighboring strings are not accidentally muted, with the thumb resting on the back of the neck for leverage and the wrist kept relaxed. The six open strings, from thickest to thinnest, are E, A, D, G, B, E, and most guitars have 12 or 14 frets counted from the nut toward the soundhole.

For strumming, Martin Guitar advises mastering downstrokes first, then practicing upstrokes separately before combining both into simple patterns, moving the arm from the wrist and elbow rather than locking the joints.

Martin Guitar's guide lists four beginner-friendly chords: G6 (middle finger on the 3rd fret of the low E string, index finger on the 2nd fret of the A string, strumming all six strings), C major 7 (middle finger on the 3rd fret of the A string, index finger on the 2nd fret of the D string, skipping the low E string), E minor (middle finger and ring finger both on the 2nd fret of the A and D strings, strumming all six strings), and D suspended 2 (index finger on the 2nd fret of the G string, ring finger on the 3rd fret of the B string, skipping the low E and A strings). The guide pairs these chords with specific beginner songs it names by artist, including tracks by Bob Marley, Ben E. King, and Oasis that can be played using only this chord set.

Building a practice routine

Martin Guitar's ten practice tips emphasize frequent, short sessions over occasional long ones, recommending that players tune the guitar before every session to build ear training, set a specific goal before sitting down, and record themselves on a phone to identify strengths and weaknesses. The guide also stresses learning songs the player already enjoys to sustain motivation, and repeating problem passages in targeted bursts until they become automatic.

1. Tune the guitar and warm up with a few basic finger or scale exercises.
2. Check posture, whether seated or using a strap while standing.
3. Practice fretting single notes with curved fingers before attempting full chords.
4. Drill one chord shape at a time, then practice switching between two chords slowly.
5. Add a simple strumming pattern, starting with downstrokes before mixing in upstrokes.
6. Apply the chords and strumming to a short section of a real song.
7. Record the session on a phone to review timing and finger placement.
8. Repeat only the specific passage that caused trouble, rather than the whole song.

Free and paid learning resources

JustinGuitar.com, built by instructor Justin Sandercoe, offers more than 1,300 structured lessons on its website at no cost, ranging from a learner's first chord to advanced blues technique, according to a profile of the platform. Sandercoe launched the site in 2003 and began posting instructional videos to YouTube in December 2006, a channel that has since passed 1.5 million subscribers. A companion mobile app adds a chord-recognition engine that listens to the player, a built-in tuner, and a songbook of more than 1,500 songs with synced chords and lyrics, available through a subscription priced at $8.99 per month or $64.99 per year after a trial period; the app has more than 4.5 million users and a 4.8-star rating from over 25,000 reviews.

Yousician takes a gamified approach: players follow a moving marker across a virtual fretboard while strumming or picking, similar in feel to a rhythm video game, and the app scores timing and note accuracy in real time, according to a review by American Songwriter. Its curriculum is organized into Missions for structured learning, Workouts for targeted chord, ear-training, and scale drills, and a Song Practice mode offering both a backing-track practice option and a scored performance option. Yousician sells three subscription tiers after a seven-day free trial: Premium at $7.49 per month or $89.99 per year with one instrument and 900-plus songs and lessons; Premium+ at $11.66 per month or $139.99 per year covering five instruments and 10,000-plus songs and lessons; and a Premium+ Family tier at $17.49 per month or $209.99 per year for four tracked accounts.

Choosing between free courses and apps

Because JustinGuitar's website course is free and built around a sequenced curriculum, it suits learners who prefer following a fixed path without a subscription. Yousician's gamified, feedback-driven format, as described in the American Songwriter review, appeals to players who respond well to score-based motivation, though the review notes that app-based practice time was not specified as a fixed daily recommendation by the source; Martin Guitar's own guidance of frequent, short, goal-driven sessions applies regardless of which tool a beginner chooses.
