Even the most adventurous improvisers need to give the listener harmonic landmarks — moments where the chord changes are clearly articulated and the music feels grounded. These are signpost phrases, and knowing when and how to use them is what keeps an outside-sounding solo from feeling lost.
What you’ll get out of this lesson: You’ll understand what a signpost phrase does, how to construct one that lands cleanly on the chord tones, and how to place them in a solo to give the listener — and yourself — clear points of harmonic reference.
Why Signposts Matter
When you’re playing freely over a chord progression, there’s a constant tension between forward momentum and harmonic clarity. Go too far from the chord tones for too long and the music starts to lose its grounding; resolve to the chord too often and it becomes predictable. Signpost phrases are the solution: deliberately placed moments where you land clearly on a chord tone — usually the root, third, or fifth — that tell the ear “we’re here in the harmony.” They function like chapter headings in a book: the reader (listener) always knows where they are, which makes it safe to take them somewhere unexpected in between.
Constructing a Signpost Phrase
A signpost doesn’t have to be long or complicated. A short phrase that targets the root or third of the current chord — especially at the start of a new chord in the progression — is all you need. The key is that the landing note is clearly a chord tone and arrives on a rhythmically strong position. This can be as simple as a bend that resolves to the third, or a descending run that arrives on the root at the top of the bar.
Placing Signposts Strategically
The most important moments to use a signpost are at major chord changes in the progression — for example, moving from the I chord to the IV chord, or arriving at the V chord. These are the pivot points where the harmony is most clearly changing, and landing a phrase that reflects that change tells the listener you’re tracking the harmony even if you’ve been playing more freely elsewhere.
Taking it further: Practise targeting one chord tone per chord change as you improvise over a twelve-bar blues. Don’t think about a phrase — just aim for one note that belongs to the current chord, on beat one. Once that feels natural, start building short phrases around those target notes.
Your homework: Choose two chord changes in a twelve-bar blues (the I–IV change and the V–IV change, for instance) and write down the chord tones for each. This week, every time you solo over those changes, deliberately land on one of those chord tones at the moment of the chord change. Build the habit of marking the harmonic movement before you worry about anything else.
