Harmonica Tab Converter - Turn Melody Notes into Harp Tab

Do you know a melody by its notes but not by harmonica tab? This free tool turns note names into tab for a 10-hole diatonic harmonica. Type notes like C4, E4 and G4, pick the key of your harp, and the tool shows the hole number and whether you blow or draw. You can then play the melody straight away, without working out each hole by hand.

What the Harmonica Tab Converter does

A diatonic harmonica has ten holes, and each hole gives two notes: one when you blow and one when you draw. The note you get depends on the hole, on blow or draw, and on the key of the harmonica. A player who knows a tune as note names still has to translate every note into a hole and a breath direction. That translation is slow, and it is easy to pick the wrong hole when two holes share a note name in different octaves. This converter does the translation for you. It checks every note against the full layout of a Richter-tuned diatonic harp and returns the matching hole, marked B for blow and D for draw. The result is a line of tab you can read while you play.

How harmonica tab works

Harmonica tab is much simpler than staff notation. The number tells you the hole, and a letter or sign tells you the breath. In this tool, 4B means blow into hole 4, and 4D means draw from hole 4. On a C harmonica, hole 4 blow gives C, the home note of the harp, and hole 4 draw gives D. Holes 1 to 4 cover the low octave, holes 4 to 7 cover the middle octave, and holes 7 to 10 cover the high octave. Some notes appear in more than one place. For example, G appears as hole 2 draw and hole 3 blow on a C harp. The converter picks the first matching hole in its layout, which keeps the tab consistent and easy to follow. If you prefer a different position for a repeated note, you can still use the tab as a starting point and adjust by ear.

How to use the converter

First, choose the key of your harmonica from the drop-down list. Most beginners start with a C harmonica, but the tool also covers G, D, A, E, F and Bb harps. Second, type your melody as note names separated by spaces. Write the octave number with each note, for example C4 E4 G4 C5, because the same letter in a different octave lives in a different hole. Sharps work too: write F#4 for F sharp and Bb3 for B flat. Third, press the convert button. The tool shows the tab in one line and a note-by-note list below it, so you can check each step. Copy the tab into a notebook or keep the page open while you practise.

A worked example

Take the simple melody C4, E4, G4, C5. On a C harmonica, C4 is hole 1 blow, E4 is hole 2 blow, G4 is hole 2 draw, and C5 is hole 4 blow. The converter returns 1B 2B 2D 4B. Notice how the first three notes sit close together on the harp, which is normal: the low end of a diatonic harp packs a full chord into a few holes. Now try the same melody on a G harmonica. The tool transposes the whole layout by the key of the harp, so the same notes land on different holes. That is the real value of choosing the harp key first: the tab always matches the instrument in your hand, not a generic chart.

Tips for clean, playable tab

Always include octave numbers. A bare letter like G is not enough, because G exists in three octaves on the harp. If a note shows as a dash, it is outside the range of a standard 10-hole harp, or it needs a bend. Try the note an octave higher or lower and see if the melody still works. Play the tab slowly at first and listen for wrong notes: a wrong hole usually sounds clearly out of tune with the melody in your head. Keep phrases short when you practise, and mark breath changes with a small pause. Fast passages that jump between blow and draw are the hardest part of harmonica playing, so short, repeated practice beats one long session.

Limits and common questions

This tool covers straight blow and draw notes on a Richter diatonic harp. It does not include bends, overblows or chromatic harmonica layouts, because those techniques change the pitch of a hole in ways that depend on the player. If you need a bent note, treat the tab as a guide and add the bend mark yourself. The tool is also a learning aid, not a substitute for listening: use it to get started, then trust your ear.
