Hark the Herald Angels Sing: SATB key, voices and rehearsal
Hark the Herald Angels Sing is in the CantuStudio hymn catalog. The listed theme is Christmas, and the reference key for rehearsal is F major. What follows covers the key signature, the SATB voices and a practical way to reach a draft the choir can review. This page does not print the lyrics, and it does not treat the first playback as a finished anthem.
The F major scale is F, G, A, B♭, C, D and E, with 1 flat in the key signature (B♭). The relative key is D minor. The three primary chords are I (F major); IV (B♭ major); V (C major). The full set of diatonic triads, useful when you check the harmony before rehearsal, is I F major, ii G minor, iii A minor, IV B♭ major, V C major, vi D minor, vii° E diminished. A chromatic chord can still be intentional; the list only marks what belongs to the key.
The voicing is SATB: soprano, alto, tenor and bass. Comfortable ranges for an amateur choir, before you move the key up or down for the room, are Soprano: C4 to G5; Alto: G3 to D5; Tenor: C3 to G4; Bass: E2 to C4. Those spans are a check, not a rule that replaces the director. If the congregational tune sits above the soprano or pushes the bass into the extreme low end, try the neighboring key and listen to each section on its own.
A workable path has four steps. First, enter the melody on the virtual piano, from a file or from a recording; the lyrics are not supplied here. Second, generate a four-part draft and treat it as something to mark up. Third, listen to the playback and look for parallel fifths, parallel octaves, voice crossing and wide gaps between the sections. Fourth, export MIDI or PDF once the draft is acceptable. The MusicXML file is a Pro download. After that review, the rehearsal kit can go out so each section opens its own voice on a phone.
The catalog lists this title without a separate alternate name. Neighboring hymns in the same catalog are Silent Night, Joy to the World, O Come, All Ye Faithful, O Little Town of Bethlehem and The First Noel. Public-domain note used by the catalog: Words: Charles Wesley, 1739, altered by George Whitefield, 1753. Tune: Felix Mendelssohn, 1840, adapted by William H. Cummings, 1855. Confirm the edition your choir sings before you copy parts.
Wesley’s hymn and Cummings’s adaptation
Charles Wesley published the hymn in 1739, in Hymns and Sacred Poems, with the opening line “Hark, how all the welkin rings.” “Welkin” means the heavens. George Whitefield, in his 1753 collection, replaced that line with the wording congregations know, about herald angels. Later editors, including Martin Madan, changed other lines. The version in a modern hymnal is a composite built in the eighteenth century from Wesley’s poem. It is still public domain. It is not a word-for-word copy of 1739, and a program note that says “text by Wesley, unaltered” is inaccurate. Say that Wesley wrote the hymn and that Whitefield’s generation changed the famous line.
The tune is not Wesley’s and it is not a folk carol. Felix Mendelssohn wrote it as a male-chorus section of his 1840 Festgesang, a piece for the anniversary of Gutenberg’s press, not for Christmas. He told an English publisher, in substance, that the music would not do for sacred words and would be better left with its original secular text. William H. Cummings adapted it to Wesley’s hymn anyway, in 1855. The irony is worth one sentence in rehearsal, because it explains the character: this is march-like festival music, later asked to carry a theological text. Cummings’s adaptation and Mendelssohn’s 1840 music are both public domain. A new brass fanfare written last year over the same tune is not.
Rehearse it as festival music with a light step, not as a lullaby and not as a football chant. The opening is a fanfare. The continuation is a hymn. If the choir only produces one dynamic, the fanfare and the hymn become the same shout. History gives you the contrast: a chorus written for a civic festival, adapted for church, still needing air between the chords.
Fanfare in the soprano, detachment in the bass
The soprano fanfare begins with a pickup into a rising figure and comes back down. It has to be rhythmically together or it sounds like four people starting a race. Unison the fanfare before you add chords. When the alto enters, it often takes the third below on the cadence that ends the first sentence. That third is the chord. If the altos are under pitch, the fanfare sounds minor and gloomy, which is the wrong mode for this text. Tune the third before you add volume.
Tenors have the inner moving notes, including pickups that are easy to sing late. A late tenor pickup makes the soprano sound early. Give the tenors the rhythm on one note, with the conductor’s hand, and only then the pitches. Do not let them scoop into the pickup. The line is instrumental in origin — it was written for male chorus in a festive cantata — and it speaks more clearly if the tenor treats it as a syllable with a start, not as a sigh.
Basses should be detached. The tune has a duple march pulse, and a bass who connects every beat with a legato slide will turn the march into a waltz. Short notes, clear releases, and no extra accent on every downbeat. The downbeat is already strong because the soprano fanfare lands there. Octave doubling between bass and soprano is a fault if it lasts through the fanfare; a single octave at a cadence can be fine if the inner voices keep the third. Check the draft for parallel fifths between bass and tenor where both walk down into the cadence. That walk is the usual place a generator copies one line onto the other.
Rehearsal for the pickup and the dot
The first note is a pickup, and it is late in almost every volunteer choir. They breathe on the pickup instead of before it. Practice the breath as its own event: breathe, then sing, with a beat of silence you can see. Conduct the pickup as part of the previous bar’s last beat so it has a place to sit. Once the entrance is together, look at the dotted rhythm. Many choirs turn the dot into a triplet because triplets feel easier. Speak “long-short” and make the short note truly short. If the basses lengthen the dot, everyone else will follow them into a swing that Mendelssohn did not write.
After the opening sentence, the hymn settles into a more regular phrase. Do not keep the fanfare dynamic. Mark a lower step for the middle of the stanza and a return of energy on the last line, only if the dot is still clean. A crescendo on a messy dot multiplies the mess. Sectionals help: sopranos and altos on the fanfare thirds, tenors and basses on the pickups, then a short full choir pass. Ten minutes on the first four bars is worth more than a run-through of all the stanzas.
If the congregation sings, they will drag the dot even more than the choir. Decide in advance whether the choir will lead with a clear soprano and a light bass, or whether you will drop to unison on the fanfare so the assembly has one rhythm to follow. A thick SATB chord with four different releases is not leadership. You can still keep the full harmonization for a stanza the choir sings alone.
F major, unless the fanfare top is easy in G
The catalog reference is F major, one flat. The fanfare sits in a range where an amateur soprano can be precise, and the bass stays in a region that can be short and clear rather than boomy. G major is a common printed key and it is exciting. It is also one step higher on the note that already wants to be yelled. Take G only after a soprano has sung the top of the fanfare in the room, softly, without a grab. If the soft version does not exist, the loud version in the service will be sharp.
E-flat is a step below F and can work for a very young soprano section, but it can turn muddy if the basses are few and the room is carpeted. Hear the bass release in the empty church before you commit to E-flat. Whatever you choose, generate the parts in that key and put the same key on the rehearsal tracks. A choir that learns the fanfare in F will not reliably sing it in G because the conductor asks at the door. The pickup, which was already late, will be later.
Questions before the Mendelssohn adaptation
Is the first line Wesley’s original?
The 1739 hymn opened “Hark, how all the welkin rings.” George Whitefield’s 1753 collection changed the line to the familiar herald-angels wording. Martin Madan and others altered later lines. The text most choirs sing is a composite, not a photograph of the 1739 poem. The underlying Wesley text and the eighteenth-century alterations are public domain.
Did Mendelssohn write a Christmas carol?
He wrote a male-chorus number in the 1840 Festgesang for the Gutenberg anniversary. William H. Cummings adapted that music to Wesley’s hymn in 1855. Mendelssohn had said the tune was not suited to sacred words. The adaptation is still his melody in Cummings’s hands, and both the 1840 music and the 1855 adaptation are public domain.
What key should an amateur choir use?
F major is the catalog reference. The opening fanfare sits in a speaking range and the bass can stay detached without going muddy. G major is the brighter hymnal key. Take G only if the sopranos can sing the top of the fanfare without forcing. The deciding note is that top, not the pianist’s preference.
What rhythmic habit ruins the opening?
A late pickup and a dotted rhythm that has collapsed into triplets. Breathe before the fanfare, put the pickup with the conductor, and keep the dot short. Basses who sit on the dot will drag the whole choir into a swing feel that the tune does not have.
