Baritone for Modern Jazz

The short answer

Baritone for modern jazz. Phrasing in the lower register.

In modern jazz the baritone is a voicing machine. Extended chords, drop-2 shapes and walking movement all sit in a warmer, fuller register, and because a Bacci keeps the low end defined, complex harmony stays legible instead of blurring together.

It changes how you phrase. Single-note lines gain weight and vocal quality low down, chord-melody carries its own foundation, and a solo guitar performance sounds complete on its own.

With the dual output you can take that literally: guitar and bass, two independent signals from a single instrument.

The maker

It all begins with one man, and his hands.

Bruno Bacci is a Tuscan luthier with a background in metallurgy, woodworking and design. A guitarist first, he became a builder after a hand injury and trained at the violin-making school of Cremona, where Stradivari had worked three centuries earlier.

He does not begin with a shape. He begins with the sound he wants to hear and builds the instrument around it, testing each piece of wood by hand as though in conversation with it. Every Bacci is made individually and is backed for life by Bruno himself.

His first guitar, a Telecaster he built as a young man, carried no name. He could not write Fender because it was not their instrument. He could not write Bacci because it was not his design either. That is why he began creating instruments that could only be his.

In their words

What players say.

Put flats on it and it sounds like an old P bass. Put round-wounds on it and there’s a lot of bite.

The amount of low end and even saturation coming from this bass is insane.

When I play it, I don’t really miss the bass player.

Questions.

Does a baritone work for jazz chord-melody?

Very well. The lower register gives chord-melody its own bass foundation, so a solo arrangement sounds full without accompaniment.

Do extended jazz chords get muddy on a baritone?

Not on a Bacci. The longer scale and careful build keep even dense voicings clear and defined.

Which jazz players use the Bacci baritone?

Matteo Mancuso, widely called one of the best guitarists in the world, plays and praises the Bacci baritone.

Can a baritone replace having a bassist?

In many settings, yes. Mancuso said he doesn't miss the bass player, and the Bacci dual output makes guitar-plus-bass from one instrument literal.
