Writing Guitar Melodies: Target Tones, Guide Tones, and Phrasing

What Makes a Melody Musical

Play C major from bottom to top, then back down. That's not a melody — it's a scale demonstration. Now play C, skip to E, hold it, drop to D, resolve to C. That's a melody fragment. The difference is intention: specific notes chosen for specific reasons, with space between them.

Three things make a melodic phrase feel musical rather than random: it moves toward destinations (target tones), it uses tension and release (approach notes and resolutions), and it breathes (silence and phrase length). Most players have the first problem — they run scales without knowing where they're going. Every note in a strong melody is either arriving somewhere or preparing the arrival.

Target Tones

A target tone is a chord tone — the root, 3rd, 5th, or 7th of the underlying chord — that you land on at a rhythmically strong point, usually beat 1 of a new chord change. When the harmony moves from one chord to the next, landing on a note from the new chord on the downbeat creates a sense of arrival. Landing on a non-chord tone on that same beat creates tension.

In a I-IV-V-I progression in C major: when you land on beat 1 of the C chord, aim for C, E, or G. When the harmony moves to F, aim for F, A, or C on the downbeat. These landing points anchor the melody to the harmony and make improvised lines sound composed rather than accidental.

The most powerful target tones are the 3rd and 7th — the guide tones that define chord quality. Landing on the 3rd of each chord tells the listener exactly where the harmony is, even if they can't hear the chord underneath.

Chromatic Approach Notes

A chromatic approach note is a half step above or below a target tone, played just before arriving at the target. It increases tension in the moment before resolution, making the arrival more satisfying.

If your target is E (the major 3rd of C major), you can approach it from below (E♭ → E) or from above (F → E). The chromatic approach note doesn't need to be in the scale — it's a passing tone that exists purely to set up the landing. One semitone of dissonance before the target makes the consonant landing feel earned.

Bebop lines and blues phrases are constructed almost entirely from this mechanic: scale passages connected by chromatic approach notes that guide each phrase to its target tone. The chromatic note doesn't sound wrong — it sounds intentional, because it resolves immediately.

The Guide Tone Challenge

One of the most direct ways to develop harmonic hearing is to play through a standard using only the 3rds and 7ths of each chord — nothing else. This forces you to hear the harmony from its essential notes, and to find the smoothest voice leading between adjacent chords.

Take "Autumn Leaves" (a standard with clear ii-V-I motion in G major and G minor): Cm7 — F7 — B♭Maj7 — E♭Maj7 — Am7♭5 — D7 — Gm. For each chord, find the 3rd and 7th. Play just those two notes — either in sequence or as a two-note voice. As you move from chord to chord, choose whichever position keeps the voice leading as smooth as possible (minimum movement, ideally staying the same or moving by a half step).

This exercise reveals that the guide tones of adjacent chords in a ii-V-I progression swap roles: the 3rd of the ii chord becomes the 7th of the V chord, and the 7th of the V chord becomes the 3rd of the I chord. That smooth exchange is what makes ii-V-I progressions feel inevitable.

Phrase Structure: Question and Answer

Melodic phrases work in pairs: a question phrase creates tension, an answer phrase resolves it. The question ends on an unstable note — often the 2nd, 4th, or 7th scale degree — or on a chord tone of the V chord. The answer completes the thought, ending on the root or 3rd of the tonic chord.

Most great melodies use 4-bar or 8-bar phrases. The first 2 bars establish a melodic idea; the next 2 bars develop or answer it. The space between phrases — the silence — is as important as the notes. A held note followed by silence invites the listener in. A rest gives the phrase room to breathe and lets the ear anticipate what comes next.

Call and response is the simplest application: play a 1-bar melodic idea, then pause for 1 bar. Play the next idea. Pause. The alternation between sound and silence creates natural phrase structure without any conscious effort. Many great blues solos work this way: short, complete statements with deliberate space between them.

Using Scale Degrees Intentionally

Each scale degree has a specific pull or function in relation to the tonic:

• Root (1): Complete stability — the home note. Ending on the root resolves completely.
• 2nd: Gentle tension — pulls back toward the root or up to the 3rd.
• 3rd: Stable color — confirms the major or minor quality. A strong resting point.
• 4th: Significant tension — sits a half step above the major 3rd, creating a strong pull downward.
• 5th: Open stability — consonant, but not as final as the root.
• 6th: Color note — works in both directions, often melodically active.
• 7th (major): Strong leading tone — one half step below the root, creates urgency to resolve upward.
• ♭7th (minor): Softer — less urgency than major 7th; the Mixolydian/bluesy note.

Using this knowledge: if you want to create tension before a phrase ending, land on the 4th or major 7th. If you want immediate stability, land on the root or 3rd. The 5th is a middle ground — consonant but open-ended.

Melody is where theory becomes music. The concepts from every previous page — intervals, scales, modes, chord construction, diatonic progressions — all converge in the moment of creating a melodic phrase. The advanced harmony page covers the last set of tools: borrowed chords, secondary dominants, and tritone substitution, which are the mechanisms behind the most sophisticated harmonic moves in jazz and rock.
