When a piano player joined our worship team, I was genuinely excited. We had been running with guitar and an electronic keyboard player who used mostly pads and simple voicings. A trained pianist was going to add something we had been missing harmonically and I could already hear in my head how the sound of the team was going to change.
At our first rehearsal together, she asked me for her charts. I had them ready. I had been making chord charts for our guitar players for years: chord name above the lyric, strum markings where relevant, section labels in capitals. Standard worship chord chart format. I handed her the guitar chart and watched her look at it for a moment.
She did not say anything negative. She is a gracious person and she clearly knew how to read chord names. She played through the song fine. But something about her playing that first rehearsal was more cautious than I expected. More minimal. She was reading the chord names from the guitar chart and playing the most basic voicing of each one, which is not at all how she normally played. She was translating guitar notation into piano in real time and it was occupying her creative attention.
What a Guitar Chart Does Not Tell a Pianist
Guitar chord charts are written for guitar. They tell you the chord name and roughly when it appears in the song. They do not tell you how to voice the chord, which notes to emphasize, where to put the root in relation to the other voices, or how to distribute the notes across two hands. A guitarist reads the chord name and plays the shape they know for that chord. A pianist reading the same chord name has dozens of voicing options and needs more context to understand which approach fits the song.
The main things I was not providing were voicing suggestions and bass note guidance. On piano, the left hand typically covers the bass register and the right hand covers the middle and upper voices. How you distribute the notes of a chord across those two hands affects the character of the sound significantly. A full root-position voicing sounds different from an open voicing with the root in the bass and the third and seventh spread across the upper range. Both are valid but they create a different texture in the band.
I had never thought about any of this because I am a guitarist. Guitar chord voicings are determined largely by the physical layout of the instrument. You learn the shapes and they come with built-in voice distribution. Piano voicings are a compositional choice and they require guidance when someone else is writing the chart.
What I Learned About Piano Voicings
The Piano Chords tool was where I started building a real understanding of how the same chord names I was already using translated into piano voicing options. The tool shows common piano voicings for any chord you look up, displayed on a keyboard diagram so you can see exactly which notes are involved and how they are distributed.
What I realized fairly quickly is that many of the chord voicings used on piano in worship contexts are more open and spread than the equivalent guitar chord. Where a guitar G chord might double the root and the fifth in a relatively compact shape, a piano Gadd9 voicing might have the root in the bass, skip a few octaves, and then spread the third, fifth, and ninth across the right hand in a wide, resonant open voicing. That wide voicing sits in the mix very differently from the guitar chord and knowing that helped me think about how the two instruments should relate to each other.
How Our Charts Changed
After working through the piano chord voicings for our regular repertoire, I started adding a brief voicing note to the charts I created for our keys player. Not full piano notation but a simple indication: open voicing, root-fifth in left hand, or whatever the guidance was for that particular moment in the song. She said it made a noticeable difference in how quickly she could settle into the feel of a song rather than making real-time decisions about voicing while also tracking the structure and the worship leader.
The Chord Diagram Lookup is still the reference I point guitar players to when they need to see a new chord shape. The Piano Chords tool is what I now point our keys player to when she wants to see voicing options for a chord she has not worked with recently. Having both resources available has made us a more musically literate team overall, because more of us now understand how the same chord looks and feels across different instruments.
