What are the altos’ lowest notes?
While my primary focus with this hymns stats blog has been to explore how the hymns are used in sacrament meetings, a secondary focus is to look at the music itself. I have already done a handful of posts on the music of the hymns, such as the highest alto notes and [the lowest soprano notes](/posts/lowest_soprano]. In this years-overdue post, we’ll explore the lowest notes the alto line sings. Mark Mitchell has already done fantastic work related to this. I hope to add to what he’s reported already.
Here’s a plot that shows the distribution of lowest also notes across all the hymns in the 1985 hymnal.
As you can see there are three main categories of low notes: G3 and A♭3, A3 through B3, and C4 and above. Let’s work through those three cateogires.
Lowest alto notes
G3
Let’s cut to the chase: the lowest note that an alto part has in the 1985 hymnal is a G3, which is the G below the treble clef. This occurs in eight different hymns for sure. Here they are in order of how common those hymns are sung as congregational hymns in sacrament meeting:
- Because I Have Been Given Much (#219)
- There Is Sunshine in My Soul Today (#227)
- In Fasting We Approach Thee (#139)
- Be Thou Humble (#130)
- Keep the Commandments (#303)
- Know This, That Every Soul Is Free (#240)
- God of Our Fathers, Known of Old (#80)
- Up, Awake, Ye Defenders of Zion (#248)
Several of these deserve some commentary. First, as mentioned I reported on the lowest soprano notes, that G3 in
There are two more in the men’s and women’s arrangements in the back of the hymnal. One is in
Because some of these hymns are pretty common, singing this record-low note happens fairly often, a little less than once every three months on average.
A♭3
The next lowest note, A♭3, is about as rare and is found in 10 hymns, including
Typical lowest notes
So, we’ve established that G3 and A♭3 are unusually low. Looking at the distribution of the lowest notes across the hymnal in the plot above, let’s move now on to the typical low end of alto lines, which is around an A3, B♭3, or B3.
A3
There are 79 hymns that have A3 as the lowest note for the altos. This includes sacrament hymns like

The trend I think is purely coincidental. I don’t think it says anything about culture, music, or anything of real significance. It’s just interesting that a lot of Christmas hymns have A3 as the lowest alto note.
B♭3
Next are hymns where the lowest alto note is a B♭3. There are 64 hymns that fit into this category. Over half the time this type of hymn is sung is as a sacrament hymn since 9 of the 28 sacrament hymns have B♭3 as the lowest alto note, including

Again, I don’t think this is a particularly meaningful insight and is probably nothing more than coincidence. But the size of that difference is pretty striking. Especially when compared to the distribution of A3 hymns, which is almost exactly even between Opening, Sacrament, and Closing hymns, with intermediate hymns being lower likely from the sheer fact that not all sacrament meetings have an intermediate hymn.
B3
The most common lowest note for altos is a B3. This is found in 94 total hymns and makes up about a quarter of the hymns sung in sacrament meeting. These include some sacrament hymns like
Highest lowest notes
Now we enter the territory of the confusingly named “highest lowest notes”. If we look at the lowest also notes across all hymns, some will be higher than others. This section looks at the ones that never go very low. If you’re a soprano and have trouble singing below a middle C, for example, this might give you an idea of what hymns you could sing alto on.
C4
There are 25 hymns that have a C4 (middle C) as the lowest alto note. The most common one by a long shot in this group is the one sacrament hymn,
C♯4
There are also 25 hymns that have C♯4 as the lowest alto note. None of these are sacrament hymns, but they do include more regular ones like
D4
Finally, 11 hymns have the highest lowest alto note have alto lines that never go below a D4.
Conclusion
In this post, I looked on the lowest notes for just the altos. I’ve shown that the lowest note that an alto would need to be able to sing in the hymnal is a G3. Some hymns though never go below a D4. Generally though, the lowest notes for altos is between A3 and Bb3.
