Arrangement Info


"Them Changes" is a standout track by Thundercat, featuring a funky, bass-driven groove that highlights Thundercat's virtuosic bass playing and unique blend of jazz, funk, and R&B influences. The lyrics explore themes of heartbreak and emotional turmoil, delivered with Thundercat's signature falsetto vocals.

Kerry Marsh's vocal jazz arrangement begins with an a cappella rendition of the song's bridge, serving as a teaser before launching into the now-iconic drums and bass groove. A hallmark of neo-soul, the dissonance between the chord changes and the melody can present challenges for vocal harmonies. This arrangement skillfully navigates these tricky spots, employing octaves and unison writing to minimize clashes, and then breaking out into lush, dense harmonies where they are most effective.

The chart concludes with a space for vocal or instrumental improv, accompanied by vocal backgrounds, ending the piece in a sudden and unconventional manner. This modern-day classic will be a hit with your vocal jazz ensemble, offering something for singers, instrumentalists, and the audience alike to enjoy.

Perfect for advanced ensembles looking to explore contemporary jazz-funk, this arrangement captures the essence of Thundercat's innovative style while providing a fresh and exciting challenge. Check out the Scoreflipper preview to see how this arrangement can elevate your group's performance and captivate your audience.

A SkyTracks Mixer gives you access to a special webpage with a MIXABLE Multi-Track player of all of the recorded parts of the demo for this arrangement.

You will receive a link to this page which you can share with your students so they can remotely access this versatile learning tool, which works in browsers on desktops and laptops as well as mobile devices.

Although SkyTracks Mixers are functional in most browsers, the developers HIGHLY recommend using a Chrome browser if possible due to its optimal handling of the high amount of audio data to be loaded. It's also recommended to close all other browser tabs while using a SkyTracks Mixer, for best results.

SkyTracks Mixers do not have looping, pitch change or tempo change functions currently, although the developers have expressed an interest in adding these capabilities when possible.

However, SkyTracks Mixers are otherwise highly versitile as a practice tool, displaying visible waveforms that help the user recognize the various sections of the arrangement that they may want to practice. They also allow for more options in hearing how different combinations of parts sound together, and for subtle adjustment of track levels for students evolving need for support during the learning process. They're also great help to vocal jazz groups missing a member in rehearsal, as their track can be used, along with any missing rhythm section parts. A metronome is included with most mixers as well, for a steady tempo reference.

Detailed instructions for how to best utilize SkyTracks Mixers for both personal practice and rehearsals are included in the SkyTracks info document you'll receive with your order. 


(Chrome browser highly recommended for best SkyTracks Mixer performance.)

Vocal Part Tracks Explained

Drastically reduce rehearsal time spent learning notes, and leave more time for music making! 

"Vocal Part Tracks" are part-learning aids for vocal jazz ensemble members. Vocal Part Tracks are currently available for nearly the entire catalog and can be ordered on each arrangement's Product Page (like this one) for $25 per pack.  

Vocal Part Tracks have each individual part (with all the various splits for S2 and Baritone divisi when used) mixed prominantly with the accompaniment parts (or other vocal parts) playing quietly for reference. 

About splits/divisi

The majority of my arrangements have at least Soprano 2 splits, and some also have Baritone splits as well.  In the case of a standard six-part SSATBaB arrangement, I'll include the following part tracks for your students:

(S1) Soprano 1 only
(S S2) Soprano splitting to Soprano 2
(A S2) Alto splitting to Soprano 2
(A) Alto only
(T) Tenor only
(T Ba) Tenor splitting to baritone
(B Ba) Bass splitting to baritone
(B) Bass only

Minus-One Tracks Explained

"Minus-One Tracks" are individual mp3 files of the full demo for each voice part (including all soprano 2 and baritone splits, when needed), in which the voice part is muted entirely, but the remainder of the parts are mixed normally.

There are multiple uses for these tracks:  

1. Students can practice singing their parts along with all the other parts, helping them work on their independence and blending skills.

2. Directors may use these in class to check whether or not students have done their part-learning homework.

3. Directors may use these (or segments of these) for auditions

4. Soloists may use the NO SOLO track to practice lyric solos or improvisation.

Accompaniment Tracks Explained

Lacking an experienced student or professional rhythm section for performance and/or rehearsal?

Accompaniment Tracks can save the day!

"Accompaniment Tracks" (formerly known here as "Rhythm Tracks") are backing recordings for selected arrangements from my catalog, available for $25.

These can be hugely helpful in the rehearsal process, even if you'll eventually have a live rhythm section with you on your performances.  Students can use the Accompaniment Tracks for sectional run-throughs when you're not with them, helping them memorize and internalize the music.  

Of course, Accompaniment Tracks are also useful in situations in which your singers are ready for a certain level of vocal literature but you lack instrumental players to accompany them effectively.

One element of the Accompaniment Tracks that is worth note here is that there are spots in many of my accompanied arrangements that are acapella, and in these spots on the Rhythm Tracks, a subtle click track is added to keep the group with the track until the rhythm section returns.  A click is also used for the count-in on arrangements that start with vocals at the very beginning.
